Create Tasks panel

[tim-schilling]

With Django Tasks being added to Django, we should add a panel to expose some meta data about an application's tasks usages.

Minimum requirements:

• Show message to install tasks if using Django <6
• Show tasks queued as a part of the request

Other ideas:

• show all event information about the tasks that are running (would require DatabaseStore or similar to store data)
• show all registered tasks
• allow a task to be queued from the api
• allow retrying of a task
• performance comparisons?!

I think we should start with the minimum. If possible we should explore how difficult the rest would be and create issues for each with the findings.

I want to give this a go!
