MCOL-454 I_S.COLUMNSTORE_FILES multi-node

Browse Source 
I_S.COLUMNSTORE_FILES returned bad filenames and NULL file sizes when
there are multiple nodes in a ColumnStore cluster

It adds an extra message call to the WriteEngine to get the file size
for that file. The I_S function will figure out which WriteEngine to
communicate with and get the file size details from it.
