Re-implement ROC-AUC. (#6747) 
* Re-implement ROC-AUC.

* Binary
* MultiClass
* LTR
* Add documents.

This PR resolves a few issues:
  - Define a value when the dataset is invalid, which can happen if there's an
  empty dataset, or when the dataset contains only positive or negative values.
  - Define ROC-AUC for multi-class classification.
  - Define weighted average value for distributed setting.
  - A correct implementation for learning to rank task.  Previous
  implementation is just binary classification with averaging across groups,
  which doesn't measure ordered learning to rank.

README.md

This folder contains testcases for XGBoost c++ core, Python package and some other CI facilities.

Directories

  • ci_build: Test facilities for Jenkins CI and GitHub action.
  • cli: Basic test for command line executable xgboost. Most of the other command line specific tests are in Python test test_cli.py
  • cpp: Tests for C++ core, using Google test framework.
  • python: Tests for Python package, demonstrations and CLI. For how to setup the dependencies for tests, see conda files in ci_build.
  • python-gpu: Similar to python tests, but for GPU.
  • travis: CI facilities for travis.
  • distributed: Legacy tests for distributed system. Most of the distributed tests are in Python tests using dask and jvm package using spark.
  • benchmark: Legacy benchmark code. There are a number of benchmark projects for XGBoost with much better configurations.

Others

  • pytest.ini: Describes the pytest marker for python tests, some markers are generated by conftest.py file.
