in ETCD-565 we have added tests to manually rotate certificate.

In the recovery test suite, depending on the order of execution we have the following failures:

 1. : [sig-etcd][Feature:CertRotation][Suite:openshift/etcd/recovery] etcd can recreate trust bundle [Timeout:15m]

Here the tests usually time out waiting for a revision rollout - couldn't find a deeper cause, maybe the timeout is not large enough.

2. : [sig-etcd][Feature:CertRotation][Suite:openshift/etcd/recovery] etcd can recreate dynamic certificates [Timeout:15m]

The recovery test suite creates several new nodes. When choosing a peer secret, we sometimes choose one that has no member/node anymore and thus it will never be recreated.

3. after https://github.com/openshift/cluster-etcd-operator/pull/1269

After the leaf gating has merged, some certificates are not in their original place anymore, which invalidates the manual rotation procedure
