bgpd: basic vty support for EVPN

Browse Source 
Introduction of EVPN address-family node that is reachable under
BGP node, like follow: address-family evpn. Under that node, only
some commands are available for configuring a neighbor or setting
some basic settings like attribute unchanged behaviour. Currently,
no vty command is available for setting NLRI entries for EVPN.
