This introduces a linter to PRs to help with code reviews and code hygiene. I've also gone ahead and fixed (or ignored) the existing lints.
I've only setup the default linters right now. There are many more options that are documented at https://golangci-lint.run/.
The GitHub Action should add appropriate annotations to the lint job for the PR. Contributors can also lint locally using `make lint`.

I have heard from some user that they have hundred thousands of `status=completed` workflow runs in their repository which effectively blocked TotalNumberOfQueuedAndInProgressWorkflowRuns from working because of GitHub API rate limit due to excessive paginated requests.
This fixes that by separating list-workflow-runs calls to two - one for `queued` and one for `in_progress`, which can make the minimum API call from 1 to 2, but allows it to work regardless of number of remaining `completed` workflow runs.
* 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.
