Web UI for investigating the email-in quarantine

[Paul Everitt]

As mentioned here:

  https://bugs.launchpad.net/karl3/+bug/397030/comments/1

...provide a Web UI for listing information about stuff flagged in pending.db as quarantined. Chris will use his judgment about how this is implemented (e.g. as a Paster composite) and what it shows (e.g. don't allow operations for now.)

I believe Chris is going to wrap up current work today then move to migration. We might make other tasks later.

A basic UI is integrated into OSI's Karl. In order to see it one needs to set the relevant parameters in karl.ini. There are currently commented out placeholders with comments. The following bin/debug session will create a monitor instance in an existing Karl:

>>> from osi.mailin_monitor import KarlMailInMonitor
>>> root['mailin'] = KarlMailInMonitor()
>>> import transaction
>>> transaction.commit()

(The evolution scripts seem like overkill for this, but we can certainly go back and add it there if we want.)

This will then create the following urls in the app:

  /mailin/quarantine

Lists all messages currently in the quarantine. Must be KarlAdmin to view.

  /mailin/quarantine/status.txt

Returns 'OK' in plain text if quarantine is empty, otherwise returns 'ERROR'. This is not a protected view. The intent is that Six Feet Up can monitor this url.

I've just checked in a patch that eliminates the need for the bin/debug tweak above. It will now work with no change to the db. Chris M astutely pointed out that I could do what I was doing with a route rather than persistence.
