bgpd: Ensure evpn local table display shows route send status

[donaldsharp]

evpn has a concept of local tables where the evpn routes are actually converted into underlying routes/neighbor table entries( or vice versa ). Then this local route is propagated to the global evpn l2vpn table and sent to the peers. Certain show commands in evpn look
operate on the local table but make the output look like the data has not been sent to the peer. This is confusing for the operator. Modify the code
such that local tables get a Local BGP table not advertised in the place where the code talks about whom has received the data or not.

Example:
torm11# show bgp l2vpn evpn route vni 1000 mac 8a:a1:cc:73:a3:ac ip 45.0.0.5 BGP routing table entry for [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] Paths: (2 available, best #2)
Local BGP table not advertised
Route [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] VNI 1000
Imported from 192.168.100.18:2:[2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5], VNI 1000

This does change the output of some commands. I am on the edge of this being of a sufficiently bad output that this fix is worth doing.

looks good

I do think this is worth doing ... there's no way to tell which kind of route is which right now, which means you could waste a good bit of time figuring out a route is local

re. the JSON discussion, how about we add a

{ …
"notes": [],
… }

and if it's local we go

{ …
"notes": ["local route only"],
…}

(i said "flags" on the call, but "notes" is probably better because "flags" sounds like it is a protocol function or something like that)

I think the lint errors need to be addressed before we merge this
