✨ Add LeaderElectionResourceLock flag and generalize leaderElectionID flag name #345

Closed m-messiah closed 1 year ago

m-messiah commented 1 year ago

What this PR does / why we need it: The PR adds a new flag --leader-elect-resource-lock to define the type of leader election resource lock (configmapleases, configmaps or leases). Current default behaviour of controller-runtime sets it to configmapleases, so the controller creates and updates two objects now - ConfigMap and Lease. Adding the flag would help operators to switch controller to use leases only to reduce load to the API and network.

The PR also deprecates the flag --le-cm-name because it was using cm in it, that could be confusing after the switch to leases; so it introduces the new flag --leader-elect-resource-name with the fallback to --le-cm-name if it is set explicitly.
