Subject: [PATCH 121/680] Keep selected columns not used in probe keys. (#19)

* Keep selected columns not used in probe keys.
* Simplify test.
* Add comments to test and align values with non-cuDF test.
* Improve gather ordering by tracking output indices from left/right tables.

Subject: [PATCH 142/680] Run TPC-H with cuDF (#24)

* Enable cudf in TPC-H queries.
* Draft work on strings conversion.
* Improved DATE / logical type support.
* Fix for join build to allow multiple batches.
* Add environment variables VELOX_CUDF_DISABLED and VELOX_CUDF_DEBUG.
* Apply tuning parameters to TPC-H queries to use larger batches when cuDF is enabled.
* Add env vars for disabling cudf / enabling debug.
* num_drivers=1, num_repeats=1
* Don't reset hashObject_ and only set finished_ to true if noMoreInput_ is true.
* Apply tuning parameters to cuDF engine.

+> # Experimental RAPIDS cuDF Backend for Velox
+> This repository is a fork of
+> [Velox](https://github.com/facebookincubator/velox) with support for [RAPIDS
+> cuDF](https://github.com/rapidsai/cudf/) as a GPU-accelerated Velox backend.
+> We are working to upstream the contents of this repository to the Velox
+> public repository. That effort is
+> tracked in [Velox issue
+> #12412](https://github.com/facebookincubator/velox/issues/12412), with a
+> description of the high level design and merge plan for upstreaming this
+> work.
+>
+> ### Quickstart
+> This repository contains a utility scripts for quickly building and running
+> Velox with the cuDF backend. To launch the CUDA container:
+> ```
+> docker-compose run -e NUM_THREADS=$(nproc) --rm adapters-cuda /bin/bash
+> ```
+> Then invoke `./build.sh` to build Velox with GPU support and run tests.
