Subject: [PATCH] mstart.sh: support read CLUSTERS_LIST from env var

so that we can avoid port conflict when we're creating serveral
clusters with different version of Ceph source code at the same
host and at the same time.

It's very convenient for several colleagues using the same
compiling host, but both of them has individual source code
directory.
