e2e: retry deploying on API-server timeouts

Browse Source 
The upgrade-tests-cephfs fails relative regularly with the following
error during intial deployment:

    timeout waiting for deployment csi-cephfsplugin-provisioner with error error waiting for deployment "csi-cephfsplugin-provisioner" status to match expectation: etcdserver: request timed out

By detecting if the API-server returned a non-fatal error, the test does
not need to abort, but can wait for completion. PollImmediate() will
still return ErrWaitTimeout once the timeout elapsed.
