Conceptually, the operator's task is just to change the pod. As it
has no influence over the role the pod will take (either the master
or a replica), it shouldn't wait for the specific role.
This fixes at least one issue, where the pod running in a single-pod
cluster has been waited for forever by the operator expecting it to
have a wrong role (since Patroni callback assiging it the original
replica role has been killed after a quick promote by the next
callback.)

Previously, the controller fetched the Oauth token once at start, so eventually the token would expire and the operator could not create new users. This commit makes the operator fetch the token before each call to the Teams API.
