node reboot.
The lvm snapshots of the bricks are mounted at /var/run/gluster/snaps/ or
/run/gluster/snaps. These paths being on a tempfs, on reboot are removed.
So when glusterd starts, we need to recreate these paths, activate the
respective logical volumes (lvm snapshots of the bricks), and mount
these logical volumes at their respective paths.

Persisting missing snapshot info on disk as well as in memory in
the following format:
-------------NODE-UUID--------------:--------------SNAP-UUID-------------=---------SNAP-VOL-ID------------:BRICKNUM:-------BRICKPATH--------:OPERATION:STATUS

927cb5fe-63da-48f5-82f6-e6a09ddc81c4:8258b18f-d408-483d-8239-204039dc6397=83a3cc05453b46b2a7eda4c9a9208638: 3 :/brick/brick-dirs/brick3: 1 : 1
This data will be stored on disk at /var/lib/glusterd/snaps/missed_snaps_list
In memory we maintain the data as a list of glusterd_missed_snap_info
in conf, the key for this list are the first two fields,
i.e NODE-UUID:SNAP-UUID.
For every NODE-UUID:SNAP-UUID, there can be multiple operations missed
on multiple bricks. So we maintain a list of glusterd_snap_op_t
for every node of glusterd_missed_snap_info
This list is maintained or updated during snapshot create, delete, and restore
operations which are the only operations that if missed, are recorded in this
list.
During snapshot create, if a node is down, or a brick is down, we don't
receive their mount point infos. snap_status of such bricks is marked as
-1, and their brick details are added to this list.
During snapshot delete, we check from originator node, if any other
nodes, holding bricks of the said snap are down. Those are also added to the list.
Also if the node is up, but the snapshot was pending for a snap
brick, and its snap_status is -1, we add that to the list too.
When a subsequent delete entry is processed for an already existing
create entry, we just mark the create entries status as done (2), and don't
add the delete entry to the list.
During snapshot restore, we check from originator node, if any other
nodes, holding bricks of the said snap are down. Those are also added to the list.
Also if the node is up, but the snapshot was pending for a snap
brick, and its snap_status is -1, we add that to the list too.
Like delete when a subsequent restore entry is processed for an already existing
create entry, we just mark the create entries status as done (2), and don't
add the restore entry to the list.

brickinfo->brick_id was introduced to establish persistence of client xlator
names and AFR chanelog attributes (http://review.gluster.org/7155). The
snapshot volumes must also use the same IDs during snapshot create and
restore to maintain persistence.
