if a Volume is defined by the operator don't add another "work" volume. (#1015)
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.

fix: pagination for ListWorkflowJobs in autoscaler (#990) (#992)
Adding handling of paginated results when calling `ListWorkflowJobs`. By default the `per_page` is 30, which potentially would return 30 queued and 30 in_progress jobs.

This change should enable the autoscaler to scale workflows with more than 60 jobs to the exact number of runners needed.

Problem: I did not find any support for pagination in the Github fake client, and have not been able to test this (as I have not been able to push an image to an environment where I can verify this).
If anyone is able to help out verifying this PR, i would really appreciate it.

Support runner groups with selected visibility in webhooks autoscaler (#1012)
The current implementation doesn't support yet runner groups with custom visibility (e.g selected repositories only). If there are multiple runner groups with selected visibility - not all runner groups may be a potential target to be scaled up. Thus this PR introduces support to allow having runner groups with selected visibility. This requires to query GitHub API to find what are the potential runner groups that are linked to a specific repository (whether using visibility all or selected).

This also improves resolving the `scaleTargetKey` that are used to match an HRA based on the inputs of the `RunnerSet`/`RunnerDeployment` spec to better support for runner groups.

This requires to configure github auth in the webhook server, to keep backwards compatibility if github auth is not provided to the webhook server, this will assume all runner groups have no selected visibility and it will target any available runner group as before

fix(#951): add exception for self-hosted label in webhook search (#953)
The webhook "workflowJob" pass the labels the job needs to the controller, who in turns search for them in its RunnerDeployment / RunnerSet. The current implementation ignore the search for `self-hosted` if this is the only label, however if multiple labels are found the `self-hosted` label must be declared explicitely or the RD / RS will not be selected for the autoscaling.

This PR fixes the behavior by ignoring this label, and add documentation on this webhook for the other labels that will still require an explicit declaration (OS and architecture). 

The exception should be temporary, ideally the labels implicitely created (self-hosted, OS, architecture) should be searchable alongside the explicitly declared labels.

code tested, work with `["self-hosted"]` and `["self-hosted","anotherLabel"]`

feat: Workflow job based ephemeral runner scaling (#721)
This add support for two upcoming enhancements on the GitHub side of self-hosted runners, ephemeral runners, and `workflow_jow` events. You can't use these yet.

**These features are not yet generally available to all GitHub users**. Please take this pull request as a preparation to make it available to actions-runner-controller users as soon as possible after GitHub released the necessary features on their end.

**Ephemeral runners**:

The former, ephemeral runners, is basically the reliable alternative to `--once`, which we've been using when you enabled `ephemeral: true` (default in actions-runner-controller).

`--once` has been suffering from a race issue #466. `--ephemeral` fixes that.

To enable ephemeral runners with `actions/runner`, you give `--ephemeral` to `config.sh`. This updated version of `actions-runner-controller` does it for you, by using `--ephemeral` instead of `--once` when you set `RUNNER_FEATURE_FLAG_EPHEMERAL=true`.

Please read the section `Ephemeral Runners` in the updated version of our README for more information.

Note that ephemeral runners is not released on GitHub yet. And `RUNNER_FEATURE_FLAG_EPHEMERAL=true` won't work at all until the feature gets released on GitHub. Stay tuned for an announcement from GitHub!

**`workflow_job` events**:

`workflow_job` is the additional webhook event that corresponds to each GitHub Actions workflow job run. It provides `actions-runner-controller` a solid foundation to improve our webhook-based autoscale.

Formerly, we've been exploiting webhook events like `check_run` for autoscaling. However, as none of our supported events has included `labels`, you had to configure an HRA to only match relevant `check_run` events. It wasn't trivial.

In contrast, a `workflow_job` event payload contains `labels` of runners requested. `actions-runner-controller` is able to automatically decide which HRA to scale by filtering the corresponding RunnerDeployment by `labels` included in the webhook payload. So all you need to use webhook-based autoscale will be to enable `workflow_job` on GitHub and expose actions-runner-controller's webhook server to the internet.

Note that the current implementation of `workflow_job` support works in two ways, increment, and decrement. An increment happens when the webhook server receives` workflow_job` of `queued` status. A decrement happens when it receives `workflow_job` of `completed` status. The latter is used to make scaling-down faster so that you waste money less than before. You still don't suffer from flapping, as a scale-down is still subject to `scaleDownDelaySecondsAfterScaleOut `.

Please read the section `Example 3: Scale on each `workflow_job` event` in the updated version of our README for more information on its usage.

feat: avoid setting privileged flag if seLinuxOptions is not null (#599)
Sets the privileged flag to false if SELinuxOptions are present/defined. This is needed because containerd treats SELinux and Privileged controls as mutually exclusive. Also see https://github.com/containerd/cri/blob/aa2d5a97c/pkg/server/container_create.go#L164.

This allows users who use SELinux for managing privileged processes to use GH Actions - otherwise, based on the SELinux policy, the Docker in Docker container might not be privileged enough.

Fix additionalPrinterColumns (#556)
This fixes human-readable output of `kubectl get` on `runnerdeployment`, `runnerreplicaset`, and `runner`.

Most notably, CURRENT and READY of runner replicasets are now computed and printed correctly. Runner deployments now have UP-TO-DATE and AVAILABLE instead of READY so that it is consistent with columns of K8s deployments.

A few fixes has been also made to runner deployment and runner replicaset controllers so that those numbers stored in Status objects are reliably updated and in-sync with actual values.

Finally, `AGE` columns are added to runnerdeployment, runnerreplicaset, runnner to make that more visible to users.

`kubectl get` outputs should now look like the below examples:

```
# Immediately after runnerdeployment updated/created
$ k get runnerdeployment
NAME                   DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE

Experimental support for ScheduledOverrides (#515)
This adds the initial version of ScheduledOverrides to HorizontalRunnerAutoscaler.
`MinReplicas` overriding should just work.
When there are two or more ScheduledOverrides, the earliest one that matched is activated. Each ScheduledOverride can be recurring or one-time. If you have two or more ScheduledOverrides, only one of them should be one-time. And the one-time override should be the earliest item in the list to make sense.

Tests will be added in another commit. Logging improvements and additional observability in HRA.Status will also be added in yet another commits.

feat: allow ephemeral runner to be optional (#498)
- Adds `ephemeral` option to `runner.spec` 
    
    ```
      ....
      template:
         spec:
             ephemeral: false
             repository: mumoshu/actions-runner-controller-ci
      ....
    ```
- `ephemeral` defaults to `true`
- `entrypoint.sh` in runner/Dockerfile modified to read `RUNNER_EPHEMERAL` flag
- Runner images are backward-compatible. `--once` is omitted only when the new envvar `RUNNER_EPHEMERAL` is explicitly set to `false`.

Resolves #457
