rabbitmqctl outputs can be multilined if some strings are too long, thus breaking the grep regexp. This can happen if container's hostname is too long. This patch inlines the rabbitmqctl output before matching the regexp Change-Id: I2a1adb2b6c60cae1c5b6b289cc938c26c0ef12bd Closes-Bug: #1773394 Signed-off-by: parasitid <parasitid@yahoo.fr>

# The output of 'rabbitmqctl -q cluster_status' looks like this:
