SDFAB-104 Support routing via next hop in single leaf pair topology

The original design principle we adopted while implementing dual-homing is only recovering local failure using pair link.
Routing via next hop is a global thing recovered by updating ECMP hashing.
However, there is no spine in the single leaf pair setup so we need additional logic to recover this using pair link.
