Running mapReduce commands through the executeReadCommand helper will cause the driver to retry the operation, as it should not inspect the command to catch mapReduce commands. To avoid this, we run mapReduce commands through the generic command helper which generally doesn't retry reads.

Since failCommand is only available on newer server versions and need a special parameter to be enabled, the configureFailPoint helper now automatically skips a test if failCommand is not available, instead of failing the test with an error.
