Document CI / CD pipelines and release workflow

[juarezr]

Problem description

• Today we have just some outdated instructions in the file release.txt
• There is no documentation about testing workflow in Github Actions, AppVeyor, travis-ci.org (discontinued)
• There is no documentation about testing workflow in Github Actions, Coveralls, PyPI, Conda-Forge, readthedocs.org

Suggestion of Roadmap

• Fix PyPI petl not up to date (1.7.4 vs 1.7.5) #583
• Migrate CI / CD workflows from travis-ci.org (discontinued) and AppVeyor to Github Actions
• Write documentation explaining the process.
  • A simple devops.md file linked in Readme.md it's a good start
• Cleanup old, outdated, and incorrect information and files.
