glusterd: Better GlusterD handshake request validation

To allow handshake requests to be validated correctly in a multi network
environment, the request validation process has been improved.

The handshake request initiator will add it's peer ID the request.

The handshake request reciever will allow a request (as before) if,
- it has no peers, or
- the request came from a known peer

Identifying the known peer is done as follows.
- If the request contains a peer ID, it is matched against the IDs in
  the peer list. If a match is found, the request is allowed.
- The address of the incoming request is matched against the peer
  addresses in the peer list. If a match is found, the request is
  allowed.
- Otherwise, the request if disallowed
