Setup automated publishing for pypi

[devraj]

pypi has a Github action to publish software releases on pypi. At the moment we are already running tests using Github actions which runs the tests against a Cloud hosted Command Centre (running in AWS).

The suggested release lifecycle should be

• A developer has a pull request for the next set of feature changes
• All tests run and pass
• Documentation is compiled and published using the Github action
• A version is tagged using semver conventions
• Release notes are published as a Github release
• Upon the release going out a job is triggered to publish the package onto pypi
• Update local tags and documentation with the links (if applicable)
