Notify services if swift.conf is modified

swift.conf contains the hash_suffix. With the current module, we have a
race condition where services can start *before* having the right hash
in swift.conf, so some objects mays be put in quarantine.

When usint swift_config (which affect swift.conf), we should restart all
services to ensure our ring is running correctly.
