SERVER-40156 Replica sets support Split Horizons

Replica sets can now respond to `isMaster` requests with
different hostnames and ports, if contacted via alternate
names using TLS.  The `horizons` field in replica set
member configurations can be used to control which
`HostAndPort` to reply with for which "horizon view" of
a replica set.
