Testing Instructions

Run core-command from this branch with MESSAGEQUEUE_REQUIRED=true environment variable
Send command query request via internal messaging, for example:

/data # redis-cli
127.0.0.1:6379> PUBLISH .commandquery.request.Random-Boolean-Device '{"CorrelationID": "14a42ea6-c394-41c3-8bcd-a29b9f5e6835", "ApiVersion": "v2", "RequestId": "e6e8a2f4-eb14-4649-9e2b-175247911369", "ContentType": "application/json"}'
(integer) 1

Verify core-command received the request and send the response back correctly:
