This removes the flag and code for the legacy GitHub API cache. We already migrated to fully use the new HTTP cache based API cache functionality which had been added via #1127 and available since ARC 0.22.0. Since then, the legacy one had been no-op and therefore removing it is safe.

* Enhance RunnerSet to optionally retain PVs accross restarts
This is our initial attempt to bring back the ability to retain PVs across runner pod restarts when using RunnerSet.
The implementation is composed of two new controllers, `runnerpersistentvolumeclaim-controller` and `runnerpersistentvolume-controller`.
It all starts from our existing `runnerset-controller`. The controller now tries to mark any PVCs created by StatefulSets created for the RunnerSet.
Once the controller terminated statefulsets, their corresponding PVCs are clean up by `runnerpersistentvolumeclaim-controller`, then PVs are unbound from their corresponding PVCs by `runnerpersistentvolume-controller` so that they can be reused by future PVCs createf for future StatefulSets that shares the same same StorageClass.

* Remove legacy GitHub API cache of HRA.Status.CachedEntries
We migrated to the transport-level cache introduced in #1127 so not only this is useless, it is harder to deduce which cache resulted in the desired replicas number calculated by HRA.
Just remove the legacy cache to keep it simple and easy to understand.
* Deprecate githubAPICacheDuration helm chart value and the --github-api-cache-duration as well
* Fix integration test
The log level -3 is the minimum log level that is supported today, smaller than debug(-1) and -2(used to log some HRA related logs).
This commit adds a logging HTTP transport to log HTTP requests and responses to that log level.
It implements http.RoundTripper so that it can log each HTTP request with useful metadata like `from_cache` and `ratelimit_remaining`.
The former is set to `true` only when the logged request's response was served from ARC's in-memory cache.
The latter is set to X-RateLimit-Remaining response header value if and only if the response was served by GitHub, not by ARC's cache.
GitHub currently has some limitations w.r.t permissions management on
runner groups as they all require org admin, however at our company
we're using runner groups to serve different internal teams (with
different permissions), thus we needed to deploy a custom proxy API with
our internal authentication to provide who has access to certain APIs
depending on the repository/runner group on a given org/enterprise
This change just allows to optionally send the GitHub API calls to an alternate custom
proxy URL instead of cloud github (github.com) or an enterprise URL with
basic authentication

* 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.
* feat: RunnerSet backed by StatefulSet
Unlike a runner deployment, a runner set can manage a set of stateful runners by combining a statefulset and an admission webhook that mutates statefulset-managed pods with required envvars and registration tokens.

This makes logging more concise by changing logger names to something like `controllers.Runner` to `actions-runner-controller.runner` after the standard `controller-rutime.controller` and reducing redundant logs by removing unnecessary requeues. I have also tweaked log messages so that their style is more consistent, which will also help readability. Also, runnerreplicaset-controller lacked useful logs so I have enhanced it.
* feat: HorizontalRunnerAutoscaler Webhook server
This introduces a Webhook server that responds GitHub `check_run`, `pull_request`, and `push` events by scaling up matched HorizontalRunnerAutoscaler by 1 replica. This allows you to immediately add "resource slack" for future GitHub Actions job runs, without waiting next sync period to add insufficient runners.
This feature is highly inspired by https://github.com/philips-labs/terraform-aws-github-runner. terraform-aws-github-runner can manage one set of runners per deployment, where actions-runner-controller with this feature can manage as many sets of runners as you declare with HorizontalRunnerAutoscaler and RunnerDeployment pairs.
On each GitHub event received, the webhook server queries repository-wide and organizational runners from the cluster and searches for the single target to scale up. The webhook server tries to match HorizontalRunnerAutoscaler.Spec.ScaleUpTriggers[].GitHubEvent.[CheckRun|Push|PullRequest] against the event and if it finds only one HRA, it is the scale target. If none or two or more targets are found for repository-wide runners, it does the same on organizational runners.
Changes:
* Fix integration test
* Update manifests
* chart: Add support for github webhook server
* dockerfile: Include github-webhook-server binary
* Do not import unversioned go-github
* Update README
Currently, after refreshing the token, the controller re-creates the runner with the new token. This results in jobs being interrupted. This PR makes sure the pod is not restarted if it is busy.
Closes#74
* feat: Repository-wide RunnerDeployment Autoscaling
This adds `maxReplicas` and `minReplicas` to the RunnerDeploymentSpec. If and only if both fields are set, the controller computes and sets desired `replicas` automatically depending on the demand.
The number of demanded runner replicas is computed by `queued workflow runs + in_progress workflow runs` for the repository. The support for organizational runners is not included.
Ref https://github.com/summerwind/actions-runner-controller/issues/10
Adds the initial version of RunnerDeployment that is intended to manage RunnerSets(#1), like Deployment manages ReplicaSets.
This is the initial version and therefore is bare bone. The only update strategy it supports is `Recreate`, which recreates the underlying RunnerSet when the runner template changes. I'd like to add `RollingUpdate` strategy once this is merged.
This depends on #1 so the diff contains that of #1, too. Please see only the latest commit for review.
Also see https://github.com/mumoshu/actions-runner-controller-ci/runs/471329823?check_suite_focus=true to confirm that `make tests` is passing after changes made in this commit.
RunnerSet is basically ReplicaSet for Runners.
It is responsible for maintaining number of runners to match the desired one. That is, it creates missing runners from `.Spec.Template` and deletes redundant runners.
Similar to ReplicaSet, this does not support rolling update of runners on its own. We might want to later add `RunnerDeployment` for that. But that's another story.
