bgpd: Add "bgp bestpath peer-type multipath-relax"

This new BGP configuration is akin to "bgp bestpath aspath
multipath-relax". When applied, paths learned from different peer types
will be eligible to be considered for multipath (ECMP). Paths from all
of eBGP, iBGP, and confederation peers may be included in multipaths
if they are otherwise equal cost.

This change preserves the existing bestpath behavior of step 10's result
being returned, not the result from steps 8 and 9, in the case where
both 8+9 and 10 determine a winner.
