'names' is an array of FQDNs. 'instances' is a map indexed by canonicalized
name. Clearly these two won't always match, so when building the final
instance array to return, make sure to look up map entries by their canonicalized
name.
In the below example, "ocp-master-5pob" is clearly found as a GCE instance
but when building the final instance array it cannot be matched as the code
is looking for "ocp-master-5pob.c.ose-refarch.internal" instead. The node
is then deleted from the cluster as it cannot be found by the cloud provider.

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)

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).
Contination of #1111
I tried to keep this PR down to just a simple search-n-replace to keep
things simple. I may have gone too far in some spots but its easy to
roll those back if needed.
I avoided renaming `contrib/mesos/pkg/minion` because there's already
a `contrib/mesos/pkg/node` dir and fixing that will require a bit of work
due to a circular import chain that pops up. So I'm saving that for a
follow-on PR.
I rolled back some of this from a previous commit because it just got
to big/messy. Will follow up with additional PRs
Signed-off-by: Doug Davis <dug@us.ibm.com>
Because of how our test environment was setup, we didn’t notice that we were assuming the load balancer hosts list to be IP addresses, while they actually are hostnames.
Also updated some comments and added a check to prevent trying to release a public IP if we don’t have one.
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).

Do not report error when deleting an attached volume
Persistent volume controller should not send warning events to a PV and mark the PV as failed when the volume is still attached.
This happens when a user quickly deletes a pod and associated PVC - PV is slowly detaching, while the PVC is already deleted and the PV enters Failed phase.
`Deleter.Deleter` can now return `tryAgainError`, which is sent as INFO to the PV to let the user know we did not forget to delete the PV, however the PV stays in Released state. The controller tries again in the next sync (15 seconds by default).
Fixes#31511
Addresses #33215.
When vCenter returns error vm not found, this is now being translated to
the appropriate error 'cloudprovider.InstanceNotFound' which indicates
to Kubernetes node controller that the VM is in fact not found.
When we are mounting a lot of volumes, we frequently hit rate limits.
Reduce the frequency with which we poll the status; introduces a bit of
latency but probably matches common attach times pretty closely, and
avoids causing rate limit problems everywhere.
Also, we now poll for longer, as when we timeout, the volume is in an
indeterminate state: it may be about to complete. The volume controller
can tolerate a slow attach/detach, but it is harder to tolerate the
indeterminism.
Finally, we ignore a sequence of errors in DescribeVolumes (up to 5 in a
row currently). So we will eventually return an error, but a one
off-failure (e.g. due to rate limits) does not cause us to spuriously
fail.

AWS: More ELB attributes via service annotations
Replaces #25015 and addresses all of @justinsb's feedback therein. This is a new PR because I was unable to reopen#25015 to amend it.
I noticed recently that there is existing (but undocumented) precedent for the AWS cloud provider to manage ELB-specifc load balancer configuration based on service annotations. In particular, one can _already_ designate an ELB as "internal" or enable PROXY protocol.
This PR extends this capability to the management of ELB attributes, which includes the following items:
* Access logs:
* Enabled / disabled
* Emit interval
* S3 bucket name
* S3 bucket prefix
* Connection draining:
* Enabled / disabled
* Timeout
* Connection:
* Idle timeout
* Cross-zone load balancing:
* Enabled / disabled
Some of these are possibly more useful than others. Use cases that immediately come to mind:
* Enabling cross-zone load balancing is potentially useful for "Ubernetes Light," or anyone otherwise attempting to spread worker nodes around multiple AZs.
* Increasing idle timeout is useful for the benefit of anyone dealing with long-running requests. An example I personally care about would be git pushes to Deis' builder component.

AWS: Support HTTP->HTTP mode for ELB
**What this PR does / why we need it**:
Right now it is not possible to create an AWS ELB that listens for HTTP and where the backend pod also listens for HTTP.
I asked @justinsb in slack and he said that this seems to be an oversight, so I'd like to use this PR as a step towards solving this.
**Special notes for your reviewer**:
I've only added a simple unit test. Are any integration tests needed? I'm not familiar with the code base.

This commit adds logic for allocating and associating a public IP, if the `—load-balancer-ip` option is not used. It will do proper management of IP’s that are allocated by this provider, so IP’s that are no longer needed/used will also be released again.
Additionally the provider can now also work with CloudStack projects and advanced (VPC) networks.
Lastly the Zone interface now returns an actual zone (supplied by the cloud config), a few logical errors are fixed and the first few tests are added.
All the functionality is extensively tested against both basic and advanced (VPC) networks.

This removes the need to manually specify the version in all but unusual
cases.
For most installs this will effectively flip the default from

AWS: Added experimental option to skip zone check
This pull request resolves#28380. In the vast majority of cases, it is appropriate to validate the AWS region against a known set of regions. However, there is the edge case where this is undesirable as Kubernetes may be deployed in an AWS-like environment where the region is not one of the known regions.
By adding the optional **DisableStrictZoneCheck true** to the **[Global]** section in the aws.conf file (e.g. /etc/aws/aws.conf) one can bypass the ragion validation.
This allows the user the set "working-dir" in their vsphere.cfg file.
The value should be a path in the vSphere datastore in which the
provider will look for vms.

Adding SCSI controller type filter for vSphere disk attach
Hot plug of disks to a SCSI controller of type lsilogic doesn't work as expected. When a device is detached from the controller, it fails to remove the device from the /dev path which makes the subsequent attaches to the node to fail. With scsi controller types lsilogic-sas or paravirtual this seems to work well. This patch filters the existing controller for these types, and if it doesn't find one, it creates a new controller for disk attach.

Lots of comments describing the heuristics, how it fits together and the

In particular, we can't guarantee correct volume placement if the set of
zones is changing between allocating volumes.
Filters can't exceed 4k, and GET requests against the GCE API are also
limited, so these break down in different ways at different cluster
counts. Fix it by introducing an advisory node-instance-prefix
configuration in the GCE provider that can hint the
EnsureLoadBalancer/UpdateLoadBalancer code (and the firewall
creation/update code). If it's not there, or wrong (a hostname that's
registered violates it), just ignore it and grab the whole project.
