glusterd: Authenticate management handshake requests
Backport of
371bb42 glusterd: Authenticate management handshake requests
from master.
Management handshake requests, which are used to validate op-version
supported by the peers, are now only allowed if,
- the glusterd doesn't have any other peer, or
- the request was sent by another peer.
This prevents the op-version of a peer being changed because of a
connection attempt by an invalid peer.
BUG: 1144978
