librbd: implement mirror image resync request API

Signed-off-by: Jason Dillaman <dillaman@redhat.com>

librbd: track if a mirror image resync has been requested

A secondary image will store its resync request to the primary
image's journal. When the local rbd mirror process detects the
flag being set, it can initiate a resync from the remote.

journal: add placeholder for marking clients are disconnected

When a client is disconnected from the journal, entries can be
pruned regardless of the affected client's commit position.
