* Change. Use `service::control` event to control services
This is more FS way. E.g. sofia sends `sofia::register` event
and add all information to headers. So now `service` script
emit `fusion::service::control` event and each service responsible
for test its own name. This also allows add in future evnets to
e.g. monitor service status like `fusion::service::satus` so it
will be possible write service which will be restart services.
* Change. rename service name from `flow` to `call_flow`
* Change. Pass pid file first. Because there really no need pass timeout.
Add. `fsc` script to be able shutdown MWI and Call Flow subscribe services.
* Change. rename `fsc` to `service`.
* Change. Use `stop` command instead of `shutdown`
