conf: remove client-rt.conf

We now automatically move non-rt clients into non-rt threads so the
client-rt.conf is obsolete.

Move the module-rt in client.conf and add conditions to disable modules.

Transparently load client.conf in case applications still specify
client-rt.conf.

Custon configuration in the client-rt.conf.d/ should be moved to
client.conf.d/

src/daemon/client.conf.in
