[PATCH v2 0/6] Add 'Event.payload' field

[Stephen Finucane]

The '/event' API endpoint is really slow due to the amount of JOINs
necessary to retrieve records from the database. Resolve this by
a static JSON representation of any embedded data in the database. This
has some disadvantages, noted in the patches, but the performance
improvement is huge and users will not notice a thing.

As a necessary side-effect of this change, events now require the REST
API be enabled. To be honest, this should have been the case from day 1
as events are currently only exposed over this API.

Changes since v1:
- Use NumberFilter for event fields to prevent the generation of large
  <select>s
- Revert changes to use the JSON renderer for '/events' as this is now
  resolved
- Multiple bug fixes and other improvements

Stephen Finucane (6):
  REST: Support embedded serializers without context
  signals: Only enable events when REST API enabled
  tests: Add events API tests
  models: Migrate event fields to JSON field
  REST: Use NumberFilter for event fields
  Revert "api: Only provide JSON version of events list"
