Support for ejson

[FossilBlade]

Clear and concise description of the problem

Mongo Data API accepts request in json and ejson(extended json).
The benefit of ejon is that it preserves the data time eg. Date filed. With json date is converted to iso string but with ejon date will be stored as Date type.

Suggested solution

A config property to choose between json and ejson.
Using this value to set the header in the request:

'Content-Type': 'application/<CONFIG_VALUE>'
