Optimize conversion to native sql for "_xxx_between" common functions in DB2 LUW and activate database processing for "_months_between"

Many of our reports use the "_months_between" common function which is locally processed in DQM. Local processing is generally a problem and we want to process as many workload as possible directly on database.

A deeper look into what happens behind the scences (file configuration/xqe/db2.sql.properties) reveals an inefficient/old implementation of the conversion of "_xxx_between" common functions to native SQL and that the function "_months_between" was disabled for database processing due to a hotsite fix in UDA. This was 6+ years ago and the defect should be fixed in DB2 LUW long ago.

Every "_xxx_between" function should be mapped to its direct database equivalent (e.g. years_between, months_between, minutes_between, seconds_between, ...) and especially the function "_months_between" should also be remapped to a database function.

    This seems not to be fully implemented in release 11.2.4 FP1, only for function "_month_between" which was an example, but not for the other "_xxx_between" functions.
