For the upgrade e2e tests, don't assume there is onle one replica.
Get the number of replicas from the deployment and wait for the
deployment to have that many available. Use the lease to determine
the leader pod and reference that.

Note that the name format of leases for operator-controller and catalogd
are quite different; this doesn't change that, as it may have an impact
on the upgrade test itself.
