      Description

      Through profiling the Avatica server, I noticed that we were spending some time resizing an ArrayList while converting MetaResultSet's to ResultSetResponse's. This was because we did not specify the capacity of the ArrayList<ResultSetResponse> during construction despite knowing what the capacity needed to be.

      We can avoid some costly array copies if we specify the capacity in the constructor.
