This adds the capability for the user to attach a reason when removing
or destroying a rule. The message will both be logged in netcontrol.log
and forwarded to the responsible plugins.
Addresses BIT-1655
This commit rewrites catch and release, fixing issues with it and making
it fully cluster capable. A dedicated netcontrol_catch_release.log is
also added.
This is not quite done yet; a few more log messages are missing. There
should hopefully not be many big issues left.
