Since we are transitioning to external cloud provider, we need a way
to use the existing cinder volume plugin (from kubelet). With external
cloud manager kubelet will be run with --cloud=provider=external and
no --cloud-config file will be in the command line. So we need a way
to load the openstack config file from somewhere.
Taking a cue from kubeadm, which currently is picking up "/etc/kubernetes/cloud-config"
https://github.com/kubernetes/kubernetes/blob/master/cmd/kubeadm/app/phases/controlplane/manifests.go#L44
let's support the scenario where we fall back to this static location if
there is no cloud provider specified in the command line.
This has been tested with local-up-cluster using the following params:
EXTERNAL_CLOUD_PROVIDER=true
CLOUD_PROVIDER=openstack
CLOUD_CONFIG=/etc/kubernetes/cloud-config

dockershim: remove the use of kubelet's internal API
We let dockershim implement the kubelet's internal (CRI) API as an
intermediary step before transitioning fully to communicate using gRPC.
Now that kubelet has been communicating to the runtime over gRPC for
multiple releases, we can safely retire the extra interface in
dockershim.
This PR also moves the legacy functions to a separate file and clean up
the interfaces.

Fix event message when processing loadbalancer update
**What this PR does / why we need it**:
When a service get updated, in func [processServiceUpdate](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/service/service_controller.go#L249), we process its LB accordingly, that is, create one if the service requests and no corresponding loadbalancer exists; and delete potential orphaned load balancer if the service does not need it any more.
But if a service does not `wantsLoadBalancer` but get error when trying to `GetLoadBalancer`, user could find an event in format of "CreatingLoadBalancerFailed..."[here](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/service/service_controller.go#L261), which would confusing users. So we should generate event info according to service type.

kubelet: imagegc: exempt sandbox image
The image GC logic currently does not consider the sandbox image to be in-use by pods, since it isn't explicitly listed in the pod spec. However, it is trivially in-use if there are any pods running on the node.
This change adds logic to exempt the sandbox image from GC by always considering it as in-use.
**Reviewer Note**
I am changing `(m *kubeGenericRuntimeManager) GetImageRef` to return the ID always rather than the first tag if it exists. Seemed ok to me. Makes some error messages a little less readable in that the ID will be printed and not the tag. Just wanted to see what reviewers think about this.

Refactor service controller to common controller pattern

This does change the retry backoff from a linear backoff to an exponential backoff. The min and max retry delay stays the same.
There was only one case where we didn't want to retry, which was when we updated the service status since that handled retries itself. In that case I moved to the common pattern of using `runtime.HandleError`.

openstack: remove orphaned routes from terminated instances
**What this PR does / why we need it**:
At the moment the openstack cloudprovider only returns routes where the `NextHop` address points to an existing openstack instance. This is a problem when an instance is terminated before the corresponding node is removed from k8s. The existing route is not returned by the cloudprovider anymore and therefore never considered for deletion by the route controller. When the route's `DestinationCIDR` is reassigned to a new node the router ends up with two routes pointing to a different `NextHop` leading to broken networking.
This PR removes skipping routes pointing to unknown next hops when listing routes. This should cause [this conditional](93dc3763b0/pkg/controller/route/route_controller.go (L208)) in the route controller to succeed and have the route removed if the route controller [feels responsible](93dc3763b0/pkg/controller/route/route_controller.go (L206)).
```release-note
OpenStack cloudprovider: Ensure orphaned routes are removed.
```
When we convert the OpenStack cloud provider to run in an external
process, we should be able to use kubernetes Secrets capability to
inject the OS_* variables. This way we can specify the cloud
configuration as a configmap, specify secrets for the userid/password
information. The configmap can be mounted as a file. the secrets can
be made available as environment variables. the external controller
itself can run as a pod/daemonset.
For backward compat, we preload all the OS_* variables, if anything
is in the config file, then that overrides the environment variables.

Rework method of updating atomic-updated data volumes
**What this PR does / why we need it**:
This change affects the way that secret, configmap, downwardAPI and projected volumes (which all use the same underlying code) implement their data update functionality.
* Instead of creating a subdirectory hierarchy that will contain symlinks to each actual data file, create only symlinks to items in the root of the volume, whether they be files or directories.
* Rather than comparing the user-visible data directory to see if an update is needed, compare with the current version of the data directory.
* Fix data dir timestamp format year
* Create `..data` symlink even when a data volume has no data so consumers can have simplified update watch logic.

Support for custom tls cipher suites in api server and kubelet
**What this PR does / why we need it**:
This pull request aims to solve the problem of users not able to set custom cipher suites in the api server.
Several users have requested this given that some default ciphers are vulnerable.
There is a discussion in #41038 of how to implement this. The options are:
- Setting a fixed list of ciphers, but users will have different requirements so a fixed list would be problematic.
- Letting the user set them by parameter, this requires adding a new parameter that could be pretty long with the list of all the ciphers.
I implemented the second option, if the ciphers are not passed by parameter, the Go default ones will be used (same behavior as now).
**Which issue this PR fixes**
fixes#41038
**Special notes for your reviewer**:
The ciphers in Go tls config are constants and the ones passed by parameters are a comma-separated list. I needed to create the `type CipherSuitesFlag` to support that conversion/mapping, because i couldn't find any way to do this type of reflection in Go.
If you think there is another way to implement this, let me know.
If you want to test it out, this is a ciphers combination i tested without the weak ones:
```
TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
```
If this is merged i will implement the same for the Kubelet.
**Release note**:
```release-note
kube-apiserver and kubelet now support customizing TLS ciphers via a `--tls-cipher-suites` flag

Fixed TearDown of NFS with root squash.
NFS plugin should not use `IsLikelyNotMountPoint()`, as it uses `lstat()` / `stat()` to determine if the NFS volume is still mounted - NFS server may use root_squash and kubelet may not be allowed to do `lstat()` / `stat()` there.
It must use slower `IsNotMountPoint()` instead, including in `TearDown()` function.

This change affects the way that secret, configmap, downwardAPI and projected
volumes (which all use the same underlying code) implement their data update
functionality.
* Instead of creating a subdirectory hierarchy that itself
will contain symlinks to each actual data file, create only
symlinks to items in the root of the volume, whether they
be files or directories.
* Rather than comparing the user-visible data directory
to see if an update is needed, compare with the current
version of the data directory.
* Fix data dir timestamp format year
* Create ..data symlink even when a data volume has no data so
consumers can have simplified update watch logic.

Call Dial in blocking mode
**What this PR does / why we need it**:
# Tests which uncover underlying problem
On the current master code:
1. comment out stub plugin server start [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/cm/deviceplugin/endpoint_test.go#L127-L128)
2. run `go test -v k8s.io/kubernetes/pkg/kubelet/cm/deviceplugin --run TestNewEndpoint --count 1`. Test succeeds.
3. run `go test -v k8s.io/kubernetes/pkg/kubelet/cm/deviceplugin --run TestRun --count 1`. Test hangs with:
> listAndWatch ended unexpectedly for device plugin mock with error rpc error: code = Unavailable desc = grpc: the connection is unavailable
`2` does not fail even though it invokes Dial and no listening server is running. It is because currently Dial is not waiting till the connection turns to Ready state. And this case does not invokes any RPC call over the `conn` returned by `Dial`
`3` hangs because this tests involves actual usage of `conn`(client) and there it does not find listening server because we dint start and deliberately stopped in `1`.
`Dial` should be using `WithBlock` option which ensures that `conn` is returned only when connection is in `Ready` state.
After using `WithBlock` in the `Dial`, in this PR, if `1`, `2` and `3` are repeated. Both, `2` and `3`, fails at `Dial`, which is expected behavior. By `fail`, I meant Dial blocks forever if `WithTimeout` is not used or otherwise, a timeout failure.

feat(fakeclient): push event on watched channel on add/update/delete
**What this PR does / why we need it**:
This PR enables watch function for kubernetes [fakeclient](1bcf0b0a22/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go (L88)).
This fake client add watchReactorFunction by wrapping [watch.NewFake](1bcf0b0a22/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go (L98)) which is a `chan Event` but actually nothing pushes objects into this channel. So all watch function called by fake client will never return or never receive any object.
This PR intercepts ReactionFunc of `Create / Update / DeleteActionImpl` and will push the requested object to channel.

**What this PR does / why we need it**:
Short circuit all predicates if one predicate fails.
I think we can add a switch to control it, maybe some scenes do not need to know all the causes of failure, but also can get a great performance improvement; if you need to fully understand the reasons for the failure, and accept the current performance requirements, can maintain the current logic. It should expose this switch to the user.

Avoid panic in Cloud CIDR Allocator
**What this PR does / why we need it**:
I suspect a race exists where we attempt to look up the CIDR for a terminating node. By the time `updateCIDRAllocation` is called the node has disappeared. We determine it does not have a cloud CIDR (i.e. Alias IP Range) and attempt to record a `CIDRNotAvailable` node status. Unfortunately we reference `node.Name` while `node` is still nil.
By getting the node before looking up the cloud CIDR we avoid the nil pointer dereference, and potentially fail fast in the case the node has disappeared.
**Which issue(s) this PR fixes**:
Fixes#58181
**Release note**:
```release-note
Avoid panic when failing to allocate a Cloud CIDR (aka GCE Alias IP Range).

Add custom volume name based on SC parameter.
At present glusterfs dynamic PVs are created with
random names. However an admin would like to have some
handle on the volume names created dynamically for
various purposes. One example would be having a filter
for sorting out PVs created for a particular storage class.
This patch enables the functionality by having a custom
volume name as a prefix to dynamic PVs. This is an optional
parameter in SC and if set, the dynamic volumes are created
in below format where `_` is the field seperator/delimiter:
customvolumeprefix_PVCname_randomUUID
