* fix: Avoid duplicate volume and mount name error for generic ephemeral volume as "work"
While manually testing configurations being documented in #1464, I discovered that the use of dynamic ephemeral volume for "work" directory was not working correctly due to the valiadation error.
This fixes the runner pod generation logic to not add the default volume and volume mount for "work" dir, so that the error disappears.
Ref #1464
* e2e: Ensure work generic ephemeral volume to work as expected
We had some dead code left over from the removal of registration runners. Registration runners were removed in #859#1207

This is intended to fix#1369 mostly for RunnerSet-managed runner pods. It is "mostly" because this fix might work well for RunnerDeployment in cases that #1395 does not work, like in a case that the user explicitly set the runner pod restart policy to anything other than "Never".
Ref #1369
This feature flag was provided from ARC to runner container automatically to let it use `--ephemeral` instead of `--once` by default. As the support for `--once` is being dropped from the runner image via #1384, we no longer need that.
Ref #1196
This fixes the said issue by additionally treating any runner pod whose phase is Failed or the runner container exited with non-zero code as "complete" so that ARC gives up unregistering the runner from Actions, deletes the runner pod anyway.
Note that there are a plenty of causes for that. If you are deploying runner pods on AWS spot instances or GCE preemptive instances and a job assigned to a runner took more time than the shutdown grace period provided by your cloud provider (2 minutes for AWS spot instances), the runner pod would be terminated prematurely without letting actions/runner unregisters itself from Actions. If your VM or hypervisor failed then runner pods that were running on the node will become PodFailed without unregistering runners from Actions.
Please beware that it is currently users responsibility to clean up any dangling runner resources on GitHub Actions.
Ref https://github.com/actions-runner-controller/actions-runner-controller/issues/1307

With the current implementation if a pod is deleted, controller is failing to delete the runner as it's trying to annotate a pod that doesn't exist as we're passing a new pod object that is not an existing resource
The unregister timeout of 1 minute (no matter how long it is) can negatively impact availability of static runner constantly running workflow jobs, and ephemeral runner that runs a long-running job.
We deal with that by completely removing the unregistaration timeout, so that regarldess of the type of runner(static or ephemeral) it waits forever until it successfully to get unregistered before being terminated.
Since #1127 and #1167, we had been retrying `RemoveRunner` API call on each graceful runner stop attempt when the runner was still busy.
There was no reliable way to throttle the retry attempts. The combination of these resulted in ARC spamming RemoveRunner calls(one call per reconciliation loop but the loop runs quite often due to how the controller works) when it failed once due to that the runner is in the middle of running a workflow job.
This fixes that, by adding a few short-circuit conditions that would work for ephemeral runners. An ephemeral runner can unregister itself on completion so in most of cases ARC can just wait for the runner to stop if it's already running a job. As a RemoveRunner response of status 422 implies that the runner is running a job, we can use that as a trigger to start the runner stop waiter.
The end result is that 422 errors will be observed at most once per the whole graceful termination process of an ephemeral runner pod. RemoveRunner API calls are never retried for ephemeral runners. ARC consumes less GitHub API rate limit budget and logs are much cleaner than before.

This eliminates the race condition that results in the runner terminated prematurely when RunnerSet triggered unregistration of StatefulSet that added just a few seconds ago.
Enhances runner controller and runner pod controller to have consistent timeouts for runner unregistration and runner pod deletion,
so that we are very much unlikely to terminate pods that are running any jobs.
There is a race condition between ARC and GitHub service about deleting runner pod.
- The ARC use REST API to find a particular runner in a pod that is not running any jobs, so it decides to delete the pod.
- A job is queued on the GitHub service side, and it sends the job to this idle runner right before ARC deletes the pod.
- The ARC delete the runner pod which cause the in-progress job to end up canceled.
To avoid this race condition, I am calling `r.unregisterRunner()` before deleting the pod.
- `r.unregisterRunner()` will return 204 to indicate the runner is deleted from the GitHub service, we should be safe to delete the pod.
- `r.unregisterRunner` will return 400 to indicate the runner is still running a job, so we will leave this runner pod as it is.
TODO: I need to do some E2E tests to force the race condition to happen.
Ref #911
Apparently, we've been missed taking an updated registration token into account when generating the pod template hash which is used to detect if the runner pod needs to be recreated.
This shouldn't have been the end of the world since the runner pod is recreated on the next reconciliation loop anyway, but this change will make the pod recreation happen one reconciliation loop earlier so that you're less likely to get runner pods with outdated refresh tokens.

This allows providing a different `work` Volume.
This should be a cloud agnostic way of allowing the operator to use (for example) NVME backed storage.
This is a working example where the workDir will use the provided volume, additionally here docker is placed on the same NVME.

* Adding a default docker registry mirror
This change allows the controller to start with a specified default
docker registry mirror and avoid having to specify it in all the runner*
objects.
The change is backward compatible, if a runner has a docker registry
mirror specified, it will supersede the default one.
