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.
