snapshot: Handshake with glusterd is not proper

        Backport of http://review.gluster.org/9664

If a snap is activated or deactivated, when a node is down,
it is not retrieving the data properly during the handshake
of glusterd

With this patch, a version check will made when a glusterd
is started running. If there is a mismach in version, then
peers will exchange the healed data.
