This patch fixes the problem of the actions runner scale set listener
pod failing every 3 seconds. See
actions/actions-runner-controller#3351
The solution is not ideal, if the primary cluster is down workflows will
not execute. The primary cluster shouldn't go down though so this is
the trade off. Lower log spam and resource usage by eliminating the
failing pods on other clusters for lower availability if the primary
cluster is not available.
We could let the pods loop and if the primary is unavailable another
would quickly pick up the role, but it doesn't seem worth it.
Closes: #57
