Closes #126 and #1986 and #4762

Changes in this PR:

  • Updates JSON and CSV support for integer values to ask cuDF to read strings and then performs casting to the requested integer type with compatibility with Spark.
  • Remove redundant CSV configs for enabling reading boolean, integer, and floating-point values

I filed a follow-on issue #4793 for handling JSON with strings containing integers.

Status

  • Implementation and updated JSON & CSV tests
  • Remove redundant csv configs
  • Fix regression in Mortgage tests
  • File follow-on issues

There were test failures in test_json_input_meta. I am investigating.

The changes in this PR exposed a bug where the code assumed that GpuTextBasedPartitionReader#readToTable would return a table with the read schema projection applied, and this was not the case for the JSON implementation. This is now fixed.
