Subject: [PATCH] rabbitmq-cluster: always use quiet flag for eval calls
On older rabbitmq versions, rabbitmqctl appends "...done." at the end
of the output. However we expect eval without this extra output so it
can be used for further processing. The -q option to rabbitmqctl
suppresses the extra output, so ensure we always pass that when
calling eval.
Resolves: RHBZ#1659072
