   ### Description
   
   Recent refactors to MSQ introduced a sanity check to verify that the query 
ID received by the worker during its communication with the controller is 
correct. However, there was a pre-existing bug in Druid where the query ids for 
each individual stage can be populated with random UUIDs instead of the correct 
value. Upgrade/Downgrade between any version till or before Druid 30 where the 
newer version runs a worker task, while the older version runs a controller 
task can fail. This PR removes that verification check till its safe to add it 
back.
