Service controller / gce loadbalancer logging cleanup
**What this PR does / why we need it**:
From https://github.com/kubernetes/kubernetes/issues/52495, while looking into the potential scalability issue service controller may have, I found it really hard to debug as the log sometimes doesn't reference which LB it is for, or sometimes it just doesn't log at all. It get even harder that in correctness CIs we reduce verbose level to v1:
67bc30718f/jobs/env/ci-kubernetes-e2e-gce-scale-correctness.env (L16).

This fixes some scope isses that were introduced by shadowing vars inside anonymous functions as well as using a naked return.
Fixed by using unique err names and explicitly returning errors.
Additional improvement is using the HomeDir() util function provided by client-go instead of including a helper function at the bottom of this example.

This updates the create-update-delete-deployment example with the following:
Make use of client-go retry util in Update() steps instead of simple for loops.
Using RetryOnConflict is generally better practice as it won't become stuck in a retry loop and uses exponential backoff to prevent exhausting the apiserver.
Instead of changing annotations to demonstrate Updates/Rollbacks, change the container image as it is less confusing for readers and a better real-world example.
Improve comments and README to reflect above changes.

This updates the create-update-delete-deployment example with the following:
Add rollback step to demonstrate rolling back deployments with client-go.
Modify the for-loops used in both Update steps to Get() the latest version
of the Deployment from the server before attempting Update().
This is necessary because the object returned by Create() does
not have the new resourceVersion, causing the initial Update() to always fail
due to conflicting resource versions. Putting the Get() at the top of the
loop seems to fix this bug.
Make -kubeconfig flag optional if config is in default location, using the
same method found in the out-of-cluster example.
Patch is motivated by effort to improve client-go examples.

While moving device_plugin_handler_test.go from pkg/kubelet/cm/ to
pkg/kubelet/cm/deviceplugin/, we can no longer uses cm in its tests
because that would cause a cycle dependency. To solve this problem,
I moved the main cm GetResources functionality as well as part of the
current device plugin handler Allocate functionality into a new device
plugin handler function, GetDeviceRunContainerOptions(). This
refactoring is also needed by another PR 51895 that moves device
allocation into admission phase. Now device plugin handler Allocate()
first checks whether there is cached device runtime state and only
issues Allocate grpc call if there is no cached state available.
The new GetDeviceRunContainerOptions() function simply returns device
runtime config from the cached state. To support this change, extended the
podDevices struct and checkpoint data structure with device runtime state.

As part of the effort to move in-tree cloud providers out of kubernetes
main repository, we have identified that kube apiserver should stop
using --cloud-provider and --cloud-config parameters. One of the main
users of the parameters above is the SSH Tunneling functionality which
is used only in the GCE scenarios. We need to deprecate these flags
now and remove them in a year per discussion on mailing list.
With this change, `ssh-user` and `ssh-keyfile` are now considered deprecated
and we can remove it in the future. This means that SSH tunnel functionality
used in Google Container Engine for the Master -> Cluster communication
will no longer be available in the future.

RBD Plugin: rbdStatus only check output of successful `rbd status` run
**What this PR does / why we need it**:
Current RBDUtil.rbdStatus implementation never return error in any cases, even if command not found or `rbd status` never succeed. This PR change it to only check output of successful `rbd status` run, and return error on other cases.
Because there are maybe network problem or ceph cluster unresponsive conditions which will cause `rbd status` command to fail. We cannot assume there is no watchers on given image. It's better to return error, and let the caller to decide what to do.
