468fc8c260 MCOL-605 limit connections for I_S table 
I_S.COLUMNSTORE_FILES now caches a connection per dbroot instead of
using a connection per file.

025838629b MCOL-454 I_S.COLUMNSTORE_FILES multi-node 
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.
