Enhance RunnerSet to optionally retain PVs accross restarts (#1340)
* 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.

Ref #1286

* Update E2E test suite to cover runner, docker, and go caching with RunnerSet + PVs

Yusuke Kuoka a3072c110d Prevent runnerset pod unregistration until it gets runner ID
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.

Adding a default docker registry mirror (#689)
* 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 (#629)
* 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.

Resolves #613
Ref #612

* Upgrade controller-runtime to 0.9.0

* Bump Go to 1.16.x following controller-runtime 0.9.0

* Upgrade kubebuilder to 2.3.2 for updated etcd and apiserver following local setup

* Fix startup failure due to missing LeaderElectionID

* Fix the issue that any pods become unable to start once actions-runner-controller got failed after the mutating webhook has been registered

* Allow force-updating statefulset

* Fix runner container missing work and certs-client volume mounts and DOCKER_HOST and DOCKER_TLS_VERIFY envvars when dockerdWithinRunner=false

* Fix runnerset-controller not applying statefulset.spec.template.spec changes when there were no changes in runnerset spec

* Enable running acceptance tests against arbitrary kind cluster

* RunnerSet supports non-ephemeral runners only today

* fix: docker-build from root Makefile on intel mac

* fix: arch check fixes for mac and ARM

* ci: aligning test data format and patching checks

* fix: removing namespace in test data

* chore: adding more ignores

* chore: removing leading space in shebang

* Re-add metrics to org hra testdata

Yusuke Kuoka 9d634d88ff feat: RunnerDeployment
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.

Yusuke Kuoka d8d829b734 feat: RunnerSets
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.
