[pmg-devel] [PATCH pmg-api 01/12] refactor reload_rule_db

[Stoiko Ivanov]

move the reload of pmg-smtp-filter in a sub in PMG::Utils and call it in
the only place it was used (PMG::DBTools::reload_rule_db).

This is in preparation for fixing #2371 and dkim-signing support.

Additionally an unneeded import was removed from PMG/DBTools.pm
