If shared storage is not accessible, create a flag in /var/run/gluster/
So that when /etc/cron.d/glusterfs_snap_cron_tasks is
available again, the flag will tell us, to reload
/etc/cron.d/glusterfs_snap_cron_tasks

Check if another snapshot scheduler is running before
enabling the scheduler.
Also introducing a hidden option, disable_force
"snapshot_scheduler.py disable_force" will disable the
cli snapshot scheduler from any node, even though the node
has not been initialised for the scheduler, as long as the
shared storage is mounted
This option is hidden, because we don't want to encourage
users to use all commands from nodes that are not initialised.

Making snapshot scheduler use the common storage
shared by nfs, snapshot and geo-rep. The meta volume
should be named as gluster_shared_storage, and it
should be mounted at "/var/run/gluster/shared_storage/".
Each component(nfs, snapshot, and geo-rep) should have
their own repos inside the shared storage, and perform
their operations in the shared storage

Stopped appending time-stamp in scheduled snapshots because

GlusterFS volume snapshot provides point-in-time copy
of a GlusterFS volume. Currently, GlusterFS volume
snapshots can be easily scheduled by setting up
cron jobs on one of the nodes in the GlusterFS
trusted storage pool. This has a single point failure (SPOF),
as scheduled jobs can be missed if the node running the cron
jobs dies.
The solution to the above problems is addressed in this patch.
The snap_scheduler.py helper script expects the user to install
the argparse python module before using it.
Further details for the same are available at:
