6557851: CMS: ergonomics defaults are not set with FLAG_SET_ERGO

Browse source 
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.
