snapview-server : Refresh the snapshot list during each reconnect
Currently we are refreshing the snapshot list either when there is
a request from glusterd or the very first initialization. But if
anything changed after when glusterd is down then there is no
mechanism to refresh the snashot dentries.
This patch will refresh snapshot list during each reconnect
