Make it easier to update specific keys within nested Django JSONField data.

[Michael]

Django's docs have a great example of querying nested data using double underscore syntax similar to querying across foreign keys

Dog.objects.filter(data__owner__name='Bob')

What if we wanted to update this dogs owner's name instead (without touching anything else)? Rather than doing this

dog = Dog.objects.get(pk=n)
data = dog.data
data['owner']['name'] = 'Steve'
dog.data = data
dog.save()

It would be great to do this:

Dog.objects.filter(pk=2).update(data__owner__name='Steve')

Looks like django-postgres-extensions[0] attempts to do this, but I found the library to be unstable on 1.11.

This is kind of related to #24709 but for JSONField instead of ArrayField.

Is this ticket in active development ? If not, I'd like to take it back and finish this off.
