We now learn all routes inside the vrfs we also advertise routes on.
The routes are then placed in the southbound database for processing by
northd.
Routes are only selected if matching the following rules:
1. must not be a route advertised by us
2. must not be a local connected route (as we want to not learn transfer
networks)
3. the prefix must not be a link local address
However we can not reliably determine over which link we learned the
route in case we have two LRPs of the same LR on the same chassis.
For now we just assume the routes on both links are identical.
Future commits will refine this.

v3->v4:
- addressed review comments.
v2->v3:
* Set monitor conditions on sb Learned_Route table.
* Do not learn routes if Learned_Route table does not exist (upgrades).
