[ENHANCEMENT] Make the project installable and give it a CLI entrypoint

Your issue may already be reported! Please search on the issue tracker before creating one.

Describe the solution you'd like
Once I install the software I should be able to call ankerctl (not python <PATH_TO_SOME .py file>) or some other command which should invoke the click application.
I should then be able to use this CLI from any directory as the installation process (setuptools, poetry, flit, etc.) will add the console entrypoint to the PATH.
https://setuptools.pypa.io/en/latest/userguide/entry_point.html#console-scripts
This is a standard setup for python click or CLI applications.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
This doesn't necessarily require the package to be uploaded to pypi but making it installable and adding a console entrypoint would be pre-requisite to making the application publishable.

I'd be happy to submit a pull request to implement this. It should be fairly trivial to implement even without knowing the codebase.
