* filer: keep the existing peer subscription on a repeated add A cluster node add for a peer that is already followed restarted the subscription, dropping the metadata events between the two runs. * master: tell a connecting client the current cluster membership Cluster node updates are only broadcast to the clients connected at that moment. A filer that lost its master stream while a peer came back never learned about the peer, and stopped replicating its metadata for good. * test: a filer joining the master learns about the filers already there * test: a filer resubscribes to a peer that registered while it was disconnected Runs the reported sequence against real processes: filer2 leaves, filer1 is paused and its master stream is broken, filer2 registers again, and filer1 has to replicate from it after reconnecting.
