This enhances the controller to recreate the runner pod if the corresponding runner has failed to register itself to GitHub within 10 minutes(currently hard-coded).
It should alleviate #288 in case the root cause is some kind of transient failures(network unreliability, GitHub down, temporarly compute resource shortage, etc).
Formerly you had to manually detect and delete such pods or even force-delete corresponding runners to unblock the controller.
Since this enhancement, the controller does the pod deletion automatically after 10 minutes after pod creation, which result in the controller create another pod that might work.
