Fix SO Request body

Fix SO Request body

- Renamed modelNameVersionId to modelVersionId in SOModelInfo
- Removed requestID from SO Request body
	- As a result of this, an SOResponseWrapper was needed in order to
	  attach the control loop event requestId to use in the SOResponse
	  rule in drl (the requestID that is returned in the SO response
	  is a newly generated requestId with no relation to the Policy
	  control loop event requestId as per Arthur)
	- Updated drl to reflect the above mentioned change
- Updated simulator and junits to reflect changes
- Added an additional null httpResponse check/logger statement in SOManager and RestManager
