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
* runner: Remove the ability to use the deprecated `--once` flag
Ref #1196
* runner: Ability to opt-out of using --ephemeral
Although we are going to eventually remove the ability to use the legacy --once flag as proposed in #1196, there might be folks still using legacy GHES versions 3.2 or earlier.
This commit removes the existing feature flag to opt-in for --ephemeral, while adding another feature flag RUNNER_FEATURE_FLAG_ONCE to opt-in for --once so that folks stuck in legacy GHES versions
can still use ARC.
Since this change every user starts using --ephemeral by default. If they see any issues on legacy GHES instance, RUNNER_FEATURE_FLAG_ONCE=true can be set to opt-in to keep using --once, which gives one more ARC release until they upgrade their GHES instance.
But beware, we won't support legacy GHES instances forever as it's going to be a maintenance nightmare. Please upgrade!
Ref #1196
I believe this helps us focus on relatively more important issues like critical bug reports and highly-requested feature requests.

yup, lets get this merged though so we can do a release today
so that we can hopefully get enough information to diagnose the issue in case it's really a bug report, or it goes to Discussions in case it's a question.
In #1373 we made two mistakes:
- We mistakenly checked if all the runner labels are included in the job labels and only after that it marked the target as eligible for scale. It should definitely be the opposite!
- We mistakenly checked for the existence of `self-hosted` labe l in the job. [Although it should be a good practice to explicitly say `runs-on: ["self-hosted", "custom-label"]`](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#example-using-labels-for-runner-selection), that's not a requirement so we should code accordingly.
The consequence of those two mistakes was that, for example, jobs with `self-hosted` + `custom` labels didn't result in scaling runner with `self-hosted` + `custom` + `custom2`. This should fix that.

It's probably worth highlighting it's ver 0.X.X by design and that breaking changes are possible until we move it to 1.0.0

Adds some unit tests for the runner pod generation logic that is used internally by runner deployment and runner set controllers as preparation for #1282
Without that field, GKE 1.21 refuses to create the CRD
with an error message that conversionReviewVersions is mandatory.
conversionReviewVersions is a required field when creating apiextensions.k8s.io/v1 custom resource definitions.
Webhooks are required to support at least one ConversionReview version understood by the current and previous API server.

The [ListRunnerGroup API](https://docs.github.com/en/rest/reference/actions#list-self-hosted-runner-groups-for-an-organization) now add a new query parameter `visible_to_repository`.
We were doing `N+1` lookup when trying to find which runner group can be used for job from a certain repository.
- List all runner groups
- Loop through all groups to check repository access for each of them via [API](https://docs.github.com/en/rest/reference/actions#list-repository-access-to-a-self-hosted-runner-group-in-an-organization)
The new query parameter `visible_to_repository` should allow us to get the runner groups with access in one call.
Limitation:
- The new query parameter is only supported in GitHub.com, which means anyone who uses ARC in GitHub Enterprise Server won't get this.
- I am working on a PR to update `go-github` library to support the new parameter, but it will take a few weeks for a newer `go-github` to be released, so in the meantime, I am duplicating the implementation in ARC as well to support the new query parameter.
