CreateRBDMirrorBootstrapPeerWithoutPool creates a bootstrap peer for the current cluster

It creates the cephx user for the remote cluster to use with all the necessary details This function is handy on scenarios where no pools have been created yet but replication communication is required (connecting peers) It essentially sits above CreateRBDMirrorBootstrapPeer() and is a cluster-wide option in the scenario where all the pools will be mirrored to the same remote cluster

So the scenario looks like:

  1. Create the cephx ID on the source cluster

  2. Enable a source pool for mirroring - at any time, we just don't know when rbd --cluster site-a mirror pool enable image-pool image

  3. Copy the key details over to the other cluster (non-ceph workflow)
