When running Kubernetes against an installation of DevStack which
deploys the Cinder service at a path rather than a port (ex:
http://foo.bar/volume rather than http://foo.bar:xxx), the version
detection fails. It is better to use the OpenStack service catalog.
OTOH, when initialize cinder client, kubernetes will check the
endpoint from the OpenStack service catalog, so we can do this
version detection by it.

Remove cloud provider rackspace
**What this PR does / why we need it**:
For now, we have to implement functions in both `rackspace` and `openstack` packages if we want to add function for cinder, for example [resize for cinder](https://github.com/kubernetes/kubernetes/pull/51498). Since openstack has implemented all the functions rackspace has, and rackspace is considered deprecated for a long time, [rackspace deprecated](https://github.com/rackspace/gophercloud/issues/592) ,
after talking with @mikedanese and @jamiehannaford offline , i sent this PR to remove `rackspace` in favor of `openstack`

Add InstanceExistsByProviderID to cloud provider interface for CCM
**What this PR does / why we need it**:
Currently, [`MonitorNode()`](02b520f0a4/pkg/controller/cloud/nodecontroller.go (L240)) in the node controller checks with the CCM if a node still exists by calling `ExternalID(nodeName)`. `ExternalID` is supposed to return the provider id of a node which is not supported on every cloud. This means that any clouds who cannot infer the provider id by the node name from a remote location will never remove nodes that no longer exist.

Statefulsets for cinder: allow multi-AZ deployments, spread pods across zones
**What this PR does / why we need it**: Currently if we do not specify availability zone in cinder storageclass, the cinder is provisioned to zone called nova. However, like mentioned in issue, we have situation that we want spread statefulset across 3 different zones. Currently this is not possible with statefulsets and cinder storageclass. In this new solution, if we leave it empty the algorithm will choose the zone for the cinder drive similar style like in aws and gce storageclass solutions.

If this example is deployed it will automatically create one replica per AZ. This helps us a lot making HA databases.
Current storageclass for cinder is not perfect in case of statefulsets. Lets assume that cinder storageclass is defined to be in zone called nova, but because labels are not added to pv - pods can be started in any zone. The problem is that at least in our openstack it is not possible to use cinder drive located in zone x from zone y. However, should we have possibility to choose between cross-zone cinder mounts or not? Imo it is not good way of doing things that they mount volume from another zone where the pod is located(means more network traffic between zones)? What you think? Current new solution does not allow that anymore (should we have possibility to allow it? it means removing the labels from pv).
There might be some things that needs to be fixed still in this release and I need help for that. Some parts of the code is not perfect.
Issues what i am thinking about (I need some help for these):
1) Can everybody see in openstack what AZ their servers are? Can there be like access policy that do not show that? If AZ is not found from server specs, I have no idea how the code behaves.
2) In GetAllZones() function, is it really needed to make new serviceclient using openstack.NewComputeV2 or could I somehow use existing one
3) This fetches all servers from some openstack tenant(project). However, in some cases kubernetes is maybe deployed only to specific zone. If kube servers are located for instance in zone 1, and then there are another servers in same tenant in zone 2. There might be usecase that cinder drive is provisioned to zone-2 but it cannot start pod, because kubernetes does not have any nodes in zone-2. Could we have better way to fetch kubernetes nodes zones? Currently that information is not added to kubernetes node labels automatically in openstack (which should I think). I have added those labels manually to nodes. If that zone information is not added to nodes, the new solution does not start stateful pods at all, because it cannot target pods.
cc @rootfs @anguslees @jsafrane
```release-note
Default behaviour in cinder storageclass is changed. If availability is not specified, the zone is chosen by algorithm. It makes possible to spread stateful pods across many zones.

Use provided VipPortID for OpenStack LB
**What this PR does / why we need it**:
When creating an OpenStack LoadBalancer, Kubernetes will search through the tenant trying to match the LB's VIP with a port. This is problematic because multiple ports may have the same fixed IP, therefore leading to routing inconsistencies. We should use the port ID provided by the LB's response body instead.

The VirtIO SCSI driver for KVM changes the way disks appear in /dev/disk/by-id.
This adds support for the new format.
Without this, volume attaching on an openstack cluster using this kvm driver doesn't work
**Special notes for your reviewer**:
Does this need e2e tests? I couldn't find anywhere to add another openstack configuration used in the e2e tests.

openstack: remove field flavor_to_resource
I believe there is no usage about `flavor_to_resource`, and I think there is no need to build that information, too.

**Release note:**
```
NONE
```
The cloudprovider is being refactored out of kubernetes core. This is being
done by moving all the cloud-specific calls from kube-apiserver, kubelet and
kube-controller-manager into a separately maintained binary(by vendors) called
cloud-controller-manager. The Kubelet relies on the cloudprovider to detect information
about the node that it is running on. Some of the cloudproviders worked by
querying local information to obtain this information. In the new world of things,
local information cannot be relied on, since cloud-controller-manager will not
run on every node. Only one active instance of it will be run in the cluster.
Today, all calls to the cloudprovider are based on the nodename. Nodenames are
unqiue within the kubernetes cluster, but generally not unique within the cloud.
This model of addressing nodes by nodename will not work in the future because
local services cannot be queried to uniquely identify a node in the cloud. Therefore,
I propose that we perform all cloudprovider calls based on ProviderID. This ID is
a unique identifier for identifying a node on an external database (such as
the instanceID in aws cloud).

Add custom CA file to openstack cloud provider config
**What this PR does / why we need it**: Adds ability to specify custom CA bundle file to verify OpenStack endpoint against. Useful in tests and PoC deployments. Similar to what https://github.com/kubernetes/kubernetes/pull/35488 did for authentication.
**Which issue this PR fixes**: None
**Special notes for your reviewer**: Based on https://github.com/kubernetes/kubernetes/pull/35488 which added support for custom CA file for authentication.
**Release note**:
This change migrates the 'openstack' provider and 'keystone'
authenticator plugin to the newer gophercloud/gophercloud library.
Note the 'rackspace' provider still uses rackspace/gophercloud.

In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)
This method has been unused by k8s for some time, and yet is the last
piece of the cloud provider API that encourages provider names to be
human-friendly strings (this method applies a regex to instance names).
Actually removing this deprecated method is part of a long effort to
migrate from instance names to instance IDs in at least the OpenStack
provider plugin.

openstack: Implement the `Routes` provider API
``` release-note
Implement the Routes provider API for OpenStack using Neutron extraroute extension. This removes the need for flannel/etc where supported. To use, ensure all your nodes are on the same Neutron (private) network and specify the router ID in new `[Route]` section of provider config:
[Route]
router-id = <router UUID>
```
This change implements the Routes API using Neutron's "extraroute"
extension.
To use, this requires all the nodes to be on the same Neutron network
and the UUID of the Neutron router on that network.
Required cloud provider config section:
[Route]
router-id = <UUID of Neutron router>
Ensure kube-controllermanager is started with (non-default)
`--allocate-node-cidrs=true` and set `--cluster-cidr` to the POD
super-subnet (a private /16 would be reasonable).
Based on an earlier version by @timbyr (#19473)
Update EnsureLoadBalancer/UpdateLoadBalancer API to use node objects.
In particular, this allows us to take the node address directly from the
node.Status.Addresses and avoids a name -> instance lookup.

Don't rely on device name provided by Cinder
See issue #33128
We can't rely on the device name provided by Cinder, and thus must perform
detection based on the drive serial number (aka It's cinder ID) on the
kubelet itself.
This patch re-works the cinder volume attacher to ignore the supplied
deviceName, and instead defer to the pre-existing GetDevicePath method to
discover the device path based on it's serial number and /dev/disk/by-id
mapping.
This new behavior is controller by a config option, as falling back
to the cinder value when we can't discover a device would risk devices
not showing up, falling back to cinder's guess, and detecting the wrong
disk as attached.

Corect filtering of OpenStack LBaaS resources to delete
Neutron's API ignores unknown parameters. When listing pools etc, K8
attempts to filter on "LoadBalancerID", which is not a valid filter.
As such, it is ignored by Neutron, and a list of all pools is
returned. K8 then proceeds to delete each of the pools.
Instead, we now double check the resources really belong to the LB
we're trying to delete.

new pattern additions are easy.

At master volume reconciler, the information about which volumes are
attached to nodes is cached in actual state of world. However, this
information might be out of date in case that node is terminated (volume
is detached automatically). In this situation, reconciler assume volume
is still attached and will not issue attach operation when node comes
back. Pods created on those nodes will fail to mount.
This PR adds the logic to periodically sync up the truth for attached volumes kept in the actual state cache. If the volume is no longer attached to the node, the actual state will be updated to reflect the truth. In turn, reconciler will take actions if needed.
To avoid issuing many concurrent operations on cloud provider, this PR
tries to add batch operation to check whether a list of volumes are
attached to the node instead of one request per volume.
More details are explained in PR #33760
In order to be able to use new mounter library, this PR adds the
mounterPath flag to kubelet which passes the flag to the mount
interface. If flag is empty, mount uses default mount path.
This allows security groups to be created and attached to the neutron
port that the loadbalancer is using on the subnet.
The security group ID that is assigned to the nodes needs to be
provided, to allow for traffic from the loadbalancer to the nodePort
to be refelected in the rules.
This adds two config items to the LoadBalancer options -
ManageSecurityGroups (bool)
NodeSecurityGroupID (string)

openstack: Support config-drive and improve CurrentNodeName, GetZone
This PR adds support for fetching local instance metadata via config-drive (as well as querying metadata service), and surfaces some additional metadata information (from either source):
- `CurrentNodeName` now returns the OpenStack instance name, rather than the current hostname (they might not be the same)
- `GetZone` includes availability zone label in `FailureDomain`
Thanks to @kiall for a WIP implementation of the latter.
Previously the OpenStack provider just returned the hostname in
CurrentNodeName. With this change, we return the local OpenStack
instance name, as the API intended.
Config-drive is an alternate no-network method for publishing local
instance metadata on OpenStack. This change implements support for
fetching data from config-drive, and tries it before querying the
network metadata service (since config-drive will fail quickly if not
available).
Note config-drive involves mounting the filesystem with label
"config-2", so anyone using config-drive and running kubelet in a
container will need to ensure /dev/disk/by-label/config-2 is available
inside the container (read-only).
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.

**What this PR does / why we need it**:
The OpenStack LBaaS v2 api does not support filtering health monitors by pool_id, so /lbaas/healthmonitors?pool_id=abc123 will always return all health monitors in your OpenStack tenant.
This presents a problem when, in the very next block of code, we loop over the list of monitorIDs and delete them one-by-one. This will delete all the health monitors in your tenant without warning.
Fortunately, we already got the healthmonitor IDs when we built the list of pools. Using those, we can delete only those healthmonitors associated with our pool(s).
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
The main issue here was the use of v2_monitors.List(lbaas.network, v2_monitors.ListOpts{PoolID: poolID}). This is trying to filter healthmonitors by pool_id, but that is not supported by the API. It creates a call like /lbaas/healthmonitors?pool_id=abc123. The API server ignores the pool_id parameter and returns a list of all healthmonitors (which k8s then tries to delete).

openstack: Autodetect LBaaS v1 vs v2
```release-note
* openstack: autodetect LBaaS v1/v2 by querying for available extensions. For most installs, this effectively changes the default from v1 to v2. Existing installs can add "lb-version = v1" to the provider config file to continue to use v1.
```

<!-- Reviewable:end -->
This removes the need to manually specify the version in all but unusual
cases.
For most installs this will effectively flip the default from
v1 (deprecated) to v2 so conservative existing installs may want to
manually configure "lb-version = v1" before upgrading.
In OpenStack Mitaka, the name field for members was added as an optional
field but does not exist in Liberty. Therefore the current
implementation for lbaas v2 will not work in Liberty.

Rackspace improvements (OpenStack Cinder)
This adds PV support via Cinder on Rackspace clusters. Rackspace Cloud Block Storage is pretty much vanilla OpenStack Cinder, so there is no need for a separate Volume Plugin. Instead I refactored the Cinder/OpenStack interaction a bit (by introducing a CinderProvider Interface and moving the device path detection logic to the OpenStack part).
Right now this is limited to `AttachDisk` and `DetachDisk`. Creation and deletion of Block Storage is not in scope of this PR.
Also the `ExternalID` and `InstanceID` cloud provider methods have been implemented for Rackspace.
This is a better abstraction than passing in specific pieces of the
Service that each of the cloudproviders may or may not need. For
instance, many of the providers don't need a region, yet this is passed
in. Similarly many of the providers want a string IP for the load
balancer, but it passes in a converted net ip. Affinity is unused by
AWS. A provider change may also require adding a new parameter which has
an effect on all other cloud provider implementations.
Further, this will simplify adding provider specific load balancer
options, such as with labels or some other metadata. For example, we
could add labels for configuring the details of an AWS elastic load
balancer, such as idle timeout on connections, whether it is
internal or external, cross-zone load balancing, and so on.
Authors: @chbatey, @jsravn
Had to move other things around too to avoid a weird api ->
cloudprovider dependency.
Also adding fixes per code reviews.
(This is a squash of the previously approved commits)
We return an error if the user specifies a non 0.0.0.0/0 load balancer
source restriction on OpenStack, where we can't enforce the restriction
(currently).
This refactors #21431 to pull a lot of the code into cloudprovider so it
can be reused by AWS.
It also changes the name of the annotation to be non-GCE specific:
service.beta.kubernetes.io/load-balancer-source-ranges
