[PATCH 0/4] 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.

Stephen Finucane (4):
  REST: Support embedded serializers without context
  signals: Only enable events when REST API enabled
  models: Migrate event fields to JSON field
  REST: Only fetch required fields event filtering
