Typically if PK is not present we want to treat this as "denied". But sometimes it makes sense to treat this case as "allowed". In particular the combination POLKIT_ALWAYS_QUERY and POLKIT_DEFAULT_ALLOW makes a lot of sense: it means we can enable PK logic for actions where we so far bypassed the checks for root. With the new combination we can have a default policy of allowing some operation but still provide an effective hook to disable it. Also add some debug logging about PK operations and results as they are ongoing.
