AT&T has been pushing a feature for bgp-persistance. We have implementations on route reflectors available for use and would like to use bgp-persistance with our BGP connections to route reflectors. The intent would be to allow Long-lived Graceful Restart Capability to be used with ODL's BGP adaptor.

https://tools.ietf.org/html/draft-uttaro-idr-bgp-persistence-03

The author will be refreshing the draft so the version will

1. Long-lived Graceful Restart Capability should be supported.
a. Long-lived Stale Time should be set per AFI/SAFI
2. LLGR_STALE Community should be supported.
3. NO_LLGR Community should be supported.

this change is dependent on Graceful Restart Capability being available
