The internalQueryExecYieldPeriodMS and internalQueryExecYieldIterations were set to higher values on balancer suites as a best effort to avoid getting a QueryPlanKilled error during the initial command of a query (an initial command is any command other than getMore).

The error QueryPlanKilled can be thrown by queries when a moveCollection runs concurrently.
After SPM-3964, the error QueryPlanKilled can also be thrown due to range deletions happening in the background, triggered by chunk migrations.

To properly test SPM-3964, we will set both parameters to their default value and add a retry operation for a QueryPlanKilled error coming from a command different than getMore.
