In fle2_compact_setfcv.js, it is assumed that the parallel shell that will execute the setFeatureCompatibilityVersion command will finish running within 5 seconds, after which we make assertions that are predicated upon the completion of the setFCV command. If the parallel shell fails to execute the command within 5 seconds, then the subsequent assertions will fail. (Note that this issue only applies to the sharded test, which is only present in v7.0).
