helm-chart: allow configmaps instead of endpoints for leader elections…

[Gottox]

This fixes leader election in 1.5 on Openshift.

Any idea what's wrong with the tests? I can't see how my change has triggered the issue.

Can we get a similar condition also for operator roles? There should be no need even for get endpoints.

postgres-operator/charts/postgres-operator/templates/clusterrole.yaml

Line 57 in 88735a7

# to manage endpoints which are also used by Patroni

@ReSearchITEng applied!

@Gottox can you change the operator cluster role in the same way? Because the operator can also create a binding between the postgres-pod clusterrole and pod service account, but IIRC requires to have at least the same privileges for this. So if the pod role has a section for endpoints and the operator role lacks it, this operation would fail, I think.

I'm currently on vacations, will do it on monday! 😄

@Gottox any chance you can have a look at this PR again and update the cluster role? Thanks!
