      groupby.js test freezes inside the the optimizer with the latest Cost Model. The work around is to set a smaller value to groupByStartupCost.

      Reproduction: remove the CostModel override in jstests/cqf_parallel/groupby.js and run the test 

       

       resmoke run --suites cqf_parallel jstests/cqf_parallel/groupby.js
