[j-nsp] IP Monitoring/Tracking (SLA) on high end SRX

BFD is not a valid option because the other end is cisco and the customer is
using PBR, so based on their feedback they can't implement BFD along with
PBR on cisco side

How about a default 0.0.0.0/0 with a bfd-liveliness detection.

We use this for conditionally routing statics every now and then. 

Works well assuming the next-hop supports BFD; and no dynamic routing
protocol needed.
