* Improve history api performance
A new option "minimal_response" reduces the amount of data
sent between the first and last history states to only the
"last_changed" and "state" fields.
Calling to_native is now avoided where possible and only
done at the end for rows that will be returned in the response.
When sending the `minimal_response` option, the history
api now returns a json response similar to the following
for an entity
Testing:
