Actions-runner-controller: Runner registration check instantly restarting pods

[BrendanGalloway]

All runner pods are instantly terminating, likely due to the changes in #297

The controller log states:
Runner failed to register itself to GitHub in timely manner. Recreating the pod to see if it resolves the issue. CAUTION: If you see this a lot, you should investigate the root cause. See https://github.com/summerwind/actions-runner-controller/issues/288 "runner": "github-runner/flanksource-ci-runner-deployment-p6g48-pd6qg", "podCreationTimestamp": "2021-02-09 07:56:58 +0000 UTC", "currentTime": "2021-02-09T07:56:58.547Z", "configuredRegistrationTimeout": "10m0s"}
however it seems like there is some bug in this logic as the pod is not waiting 10 min to register.

A few minutes ago I started experiencing this in my testing environment. Haven't found a workaround yet.

@jwnx I ~solved~ _got past_ this by pinning the image tag to v1.17.0 instead of latest

values for helm release:

# ...
image:
  dindSidecarRepositoryAndTag: docker:dind
  pullPolicy: IfNotPresent
  repository: summerwind/actions-runner-controller
  tag: v0.17.0

Sorry everyone this seems like a bug in the main branch as @BrendanGalloway has pointed out.

Was it your production environment? If so, I got to think if we'd better change our GitHub actions workflow to update the latest docker image tag only on new releases, and use another tag for the image that is updated on every commit to the main branch.
