ceph-disk/tests: use random unused port for CEPH_MON

Fixes: http://tracker.ceph.com/issues/39066
Signed-off-by: Kefu Chai <kchai@redhat.com>
Conflicts:
	src/ceph-disk/tests/ceph-disk.sh: this change is not
cherry-picked from master. because ceph-disk was removed in nautilus. and
we need to run multiple luminous tests in parallel, hence the change.
