bgpd: do not del peer upon pg remote as change
Currently, when peer-group remote-as is removed, it
deletes all associated neighbors.
Upon re configuring peer-group remote-as, all neighbors
needs to be reconfigured.
Instead, when peer-group remote-as is remove,
cease associated peer's connection and keep in Idle state.
When the peer-group remote-as is (re)configured, trigger
BGP Peer FSM to form neighbor.
Note the connection will be initiated after start timer
expiry.
