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
**What this PR does / why we need it**:
The service controller currently uses a non-standard controller pattern that adds unneeded complexity. This PR moves the service controller to use common tools like the rate limited queue with exponential backoff versus tracking retry backoff in the cachedService object.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#55528
**Special notes for your reviewer**:
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`.

Show findmnt command output in case of error
**What this PR does / why we need it**:
We don't print the error output from the `findmnt` command, which makes it pretty hard to debug.
The current implementation just print:
`
I0115 11:59:36.078285 18230 nsenter_mount.go:168] Failed findmnt command for path /var/lib/origin/openshift.local.volumes/pods/8d723ec8-f9e9-11e7-bc52-025000000001/volumes/kubernetes.io~secret/pvinstaller-token-bxh42: exit status 1
`
With this patch, we can actually see the error:
`
I0115 12:04:30.908164 23301 nsenter_mount.go:168] Failed findmnt command for path /var/lib/origin/openshift.local.volumes/pods/8ff8bb98-f9e9-11e7-bc52-025000000001/volumes/kubernetes.io~secret/deployer-token-g4sg9: nsenter: failed to execute /findmnt: No such file or directory

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.

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.
**Which issue(s) this PR fixes**:
Fixes#57421
**Release note**:
```release-note
Correct issues that arise when volumes are mounted beneath another secret, configmap, downwardAPI or projected volume
```
