zebra: Add pass up through zapi what zebra is capable of handling
Zebra is starting to have some run-time capabilites that would be
useful to pass up to the higher level protocols so that they
can act in an appropriate manner when needed.
Send the ecmp value zebra is being run with and whether or not
we believe mpls is enabled in the kernel or not.
