Add an LR option, called "dynamic-routing-vrf-id", that allows CMS to
specify vrf table_id. The table_id will be used instead of tunnel_key
for given datapath corresponding to the LR. This also allows CMS to
share one vrf between multiple LRs.
Fixes: cb7ba9e9057c ("controller: Support user defined vrf names.")
Fixes: faf4df563f1d ("controller: Announce routes via route-exchange.")
Reported-at: https://issues.redhat.com/browse/FDP-1886
