Allows a user to request both quantity and age conditions be met prior to build discard. This means that if N max builds are set with M max age, builds will only be cleared if they exceed the given age and if their quantity exceed the N max build quantity. The feature will thus never allow build deletion to leave less builds than the N max builds set, or allow build deletion of builds under the M max age regardless of N max builds set. NOTE: This feature does nothing if Days to keep builds and/or Max # of builds to keep are empty. Setting Days to keep builds to 0 causes all builds to be seen as beyond the age limit. Setting Max # of builds to keep to 0 causes any build exceeding the age limit to be discarded.
