cli: Support to advertise PMSI Tunnel Attribute
This patch enables "gobgp" command to advertise the PMSI Tunnel
Attribute which is appended to the EVPN Inclusive Multicast Ethernet Tag
routes for example.
Usage Example:
$ gobgp global rib -a evpn add multicast 10.0.0.1 etag 10 rd 65000:100 pmsi ingress-repl 100 1.1.1.1
$ gobgp global rib -a evpn
Network Labels Next Hop AS_PATH Age Attrs
*> [type:multicast][rd:65000:100][etag:10][ip:10.0.0.1] 0.0.0.0 00:00:00 [{Origin: ?} {Pmsi: type: ingress-repl, label: 100, tunnel-id: 1.1.1.1}]
