HOSTEDCP-1081: Perform etcd recovery when etcd member data is lost

[csrwng]

What this PR does / why we need it:
When an etcd member's data has been lost, the only recourse we currently have is to do a hacky manual recovery. With this change, it is as simple as deleting the bad member's pvc and pod to restore a member.

Automates the steps described in https://issues.redhat.com/browse/HOSTEDCP-1081
