detach-murano plugin sets wrong rabbit_hosts in murano.conf

[SFilatov]

Basically, wrong function in manifest
murano.pp:
rabbit_os_host => split($amqp_hosts, ','),
which turns it into an array.

puppet murano class in init.pp:
'oslo_messaging_rabbit/rabbit_hosts' : value => $rabbit_os_host;
which sets only one host into config file
