bgpd: Add ability to match match peer <PEERGROUPNAME>

Browse Source 
Allow the end operator to match `match peer <PEERGROUPNAME>`
in a route-map.  If the end operator defines interface
based peers and peer-groups that have names that overlap
the interface based peer will match first.

Fixes: #11316
