[pmg-devel] [PATCH pmg-api 1/3] implement force_restart for cluster sync

[Dominik Csapak]

the 'force_restart' hash was unused, but it is actually necessary to
restart the pmg-smtp-filter if the custom.cf has changed

use it for saving the daemon name that needs to be restarted, this
way we can reuse it in the future to force restart other daemons
or for different reasons if we need to
