Subject: Server affinity: Retain user-requested remote server
We want to avoid splitting a replica server installation between
two hosts where possible so if a CA or KRA is requested then
we only try to install against a remote server that also provides
those capabilities. This avoids race conditions.
If a CA or KRA is not requested and the user has provided a
server to install against then use that instead of overriding it.
Extend the logic of picking the remote Custodia mode
(KRA, CA, *MASTER*) to include considering whether the
CA and KRA services are requested. If the service(s) are
not requested the the associated hostname may not be
reliable.

Subject: Server affinity: Don't rely just on [ca|kra]_enabled for installs
ca_enable and kra_enabled are intended to be used to identify that
a CA or KRA is available in the topology. It was also being used
to determine whether a CA or KRA service is desired on a replica
install, rather than options.setup_[ca|kra]

Subject: Server affinity: call ca.install() if there is a CA in the topology
This should not have been gated on options.setup_ca because we need
the RA agent on all servers if there is a CA in the topology otherwise
the non-CA servers won't be able to communicate with the CA.
