bgpd: new show cmd - bgp l2vpn evpn route detail

This command is added to provide detailed information. It will be
useful in troubleshooting as we will be able to dump all detailed info
using a single command.
"show bgp l2vpn evpn route [detail] ...". Additional filtering
can be done by providing type of the route.

Command will display the detailed content for all rd and macs-ip as
displayed by "show bgp l2vpn evpn route rd <> mac <>" for a single
rd, mac, ip from the global bgp routing table.
