glusterd/snapshot: Making snap operations crash consistent
In the events of a volume's brick being down, or a node being
down, making snap ops like create, delete, restore, and
status crash consistent.
Marking snap status of snap bricks which were not snapshotted
because the volume brick was down as -1, and not starting those
snap bricks till the snapshot is taken.
During delete bypassing lvm snapshot remove for snap bricks
whose snap status is -1
During restore bypass replacing xattrs on the snapshot bricks
whose snap status is -1. Also bumping restored volume's version
so as to handle nodes being down. On handshake of a restored
volume, passing brick's snap_status as well.
During snapshot status of the non-snapshotted brick details
display "N/A". If a node is down, the entry itself will not
be displayed.
