ipareplica: Pass ipareplica_ip_addresses to client deployment part

The IP addresses set with ipareplica_ip_addresses have not been passed
to ipaclient role for client deployment part. This resulted in not
setting the IP addresses.

The description for ipareplica_ip_addresses in the ipareplica README and
also the role modules was wrong and have been fixed to "List of IPA
replica IP addresses".
