glusterd/snapshot: Activation and De-activation of snapshot

Previously, snapshots by default were activated on creation and there was
no option to activate or deactivate them on demand.

This will allow the user to activate and deactivate on demand.
The CLI goes as follows

1) Activate the snap using a command "gluster snapshot activate <snapname> [force]"
2) Deactivate the snap using a command "gluster snapshot deactivate <snapname>"

Note: Even now the snapshot will be activated during creation.
