When we used `QueuedAndInProgressWorkflowRuns`-based autoscaling, it only fetched and considered only the first 30 workflow runs at the reconcilation time. This may have resulted in unreliable scaling behaviour, like scale-in/out not happening when it was expected.
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.
