Description Of Changes

This PR sets the proverbial packaging stage for a unified fides by updating the package name from fidesctl as well as the entry points and all specific code references to fidesctl

these are the 4 checks that are expected to fail, shipping it

Since users will need to install with pip install ethyca-fides now it would be good to do one more pypi release to fidesctl explaining the change and include a setup.py that has ethyca-fides it's requirement. That way if someone already has fidesctl as a dependency they will get the new one instead of the last release of fidesctl thinking they are getting the latest.

@sanders41 for sure, we release fidesctl at the end of every sprint now so I assume we'll have at least two more releases :)

This will also be included as part of the docs overhaul, and we can (and will) add a deprecation notice to the fides CLI for the last version so anyone still using fidesctl will be made aware of the change
