[Pulp-dev] Plugin relationship to tasks

I’ve had a chance to think about this some more this week and reread all
the emails. I think that the solution of just adding a hook is best. Each
solution seems to be imperfect and I think we still want users to interact
with objects (remotes, repositories, etc). I’d say I’m +1 on adding a hook
and -0 on the other proposals.
