Refactor MongoTransform.js (#1823)

* Split transformAtom into transfromTopLevelAtom and transformInteriorAtom

* Use single param for inArray and inObject

* Tidyness in transformKeyValue

* Add transformInteriorKeyValue

* Remove update from tranformInteriorKeyValue

* Split out transform update

* Move validation out of transfromUpdate

* Remove force paramater from transformTopLevelAtom throw error after if necessary

* Turn transformKeyValue into transfromKey since it is only used for that purpose

* Remove unnecessary stuff from transformKey

* convert transformKey to use parse format schema

* interior keys fixes

* Add test for interior keys with special names

* Correct validation of inner keys
