Reorganise example options Gauss-YEAR.py to split off database tags in their own files
Details in LHCBGAUSS-1453
The 'Gauss-YEAR.py' options now contain the setting of the beam and simulation parameters, while the DDDB and SIMCOND tags are in a dedicated file 'DBTags-YEAR.py'
In addition the qmtest for EPOS now instead of using Gauss-DEV.py so a randomly changing latest dbase per 2016 use the DBTags-YEAR.py corresponding to their name
