In some situation to debug issues, it would easier to see, which Columnstore.xml was written or used from cmapi.
So cmapi, should log in cmapi logfile, when Columnstore.xml was read
"read Config revision 13"
If the same revision was read again, no additional log entry is neeed.
If cmapi service writes to Columnstore.xml , cmapi service should log:
"write to Columnstore.xml, change Config revision to 14"
