[j-nsp] options for adding communities to an EVPN routing-instance?

[Andrey Kostin]

I was able to add ordinary communities to l2vpn NLRIs via vrf-export 
policy attached to routing-instance to allow them later pass route 
reflector's policies. The small caveat is that vrf-export overrides 
default policy generated by vrf-target and both communities (target:x:x 
and ASN:x) must be _added_ in the policy but it's documented pretty 
clear. May be it will work this way for evpn as well.

WBR,
Andrey
