calcite-avatica [CALCITE-2322] Add fetch row count support

This resurrects https://github.com/apache/calcite-avatica/pull/49, updating @kminder 's existing work per guidance from CALCITE-2322.

The purpose of this change is to add support for configurable "fetch size"/ "fetch row count". Currently, setting fetchSize has no effect, because avatica always uses a hardcoded default value. This PR resolves that issue.

Hi @zabetak / @zacMode . Any idea when this could be merged or if I could help move this through? I ran into this issue (fetch size stuck at 100) as well which isn't working for very large size results over HTTP.
