Fix socket path pattern match

The old regular expression for socket path can't catch the example
"ceph-mon.www-2.abc.com.asok", if we use the old regular expression, the
cluster_name,service_type,service_id will be incorrect.
The new regular expression  "^(.+)-(mon|osd|mds)\.(.+)\.asok$" can catch the
example and I think  "(mon|osd|mds)" will match all service type in ceph.
