Changes to run dbs2/dbs3 back to back in a mix mode, i.e. aggregate results from both system
Skip init of dbs_global name since it will be provided by DAS mapping; skip API if no URL is provided (when I run DBS2/DBS3 together using DBS2 local instances in DSB3 has no sense and dbs3 module can throw empty url
Pass plugin name into das mapping dbs instance method, to allow distinguish DBS instnaces names from DAS maps; add hack to match cms_dbs_prod_global with prod instance of DBS3
Pass plugin name into das mapping methods to properly get DBS instance names
Update
