Switch to rabbitmq fqdn hostnames and pass proper CA info

With this change we make sure that the 'RABBITMQ_NODENAME' is the fqdn
and that we use it when connecting to the node itself via rabbitmqctl.
We also make sure we set the CA to the one defined in the InternalTLSCAFile
template parameter.

Testing protocol is described in the parent change
("I4f853de3b532b3b5e71d29aa621a2925c3885393")
