Returns objects where any of the given keys are in the data. Uses the SQL
operator ``?|``. For example::
>>> Dog.objects.create(name='Rufus', data={'breed': 'labrador'})
>>> Dog.objects.create(name='Meg', data={'owner': 'Bob'})
>>> Dog.objects.create(name='Fred', data={})
>>> Dog.objects.filter(data__has_any_keys=['owner', 'breed'])
