Boefje scanning frequency support in scheduler

[jpbruinsslot]

Pre-Review

Since this PR's is blocked by changes to the katalogus (see #3065) I'm setting this PR's in review to gather feedback on the changes that have been made, and that expectations are met. Please note the TODO in the code on the parts where those changes of the katalogus are expected and need to be implemented.

Changes

Based on the event of new or enabled boefjes a schedule is created when that boefje has a specified interval of execution (this is supplied by the boefje.json).

Before

In the BoefjeScheduler before we would only check for enabled and new boefjes. For an enabled boefje the scheduler will gather all the OOI's this boefje can run on and will create BoefjeTask objects for this (boefje * ooi = boefje tasks).

After

Now in addition to this we will check for enabled boefjes (check_new_boefjes) and create a Schedule for any boefje that has a interval specified.

Just a few remarks; skeleton looks good

This PR is at the moment blocked because of #3065 and the implementation of the manifest for a boefje

[jpbruinsslot]

This PR is put on hold and precedence is given to: #3529

This PR allows for an interval/schedule to be defined for a boefje that runs without an ooi to specifically run on. Meaning the BoefjeTask only references a Boefje not an input ooi. Meaning the task runner makes the decision on what to execute this boefje on.
