My use case: I'd like to use hosted BitBucket runners for running my BB pipelines. However, I don't want the runners to be active 24x7 as there's no need. Instead, I'd like to get a trigger (a webhook of some sort) that lets me know that a pipeline is waiting for a runner. Once I get the trigger, I autoscale my instances to at least one instance what'd allow the runner to run the pipeline. The pipeline should also have a timeout configuration, so it fails if no runners are available in xxx minutes.
