6557851: CMS: ergonomics defaults are not set with FLAG_SET_ERGO Summary: Default values set by cms ergonomics are set with FLAG_SET_DEFAULT so down stream the values look like the default values and affect how later parameters are set. Set these values with FLAG_SET_ERGO instead and adjust how later parameters are interpreted. Reviewed-by: iveresov, apetrusenko, pbk, ysr
