Separating funcx-endpoint and funcx packages, but under same namespace

[theodore-ando]

• pip install funcx installs the sdk

• pip install funcx-endpoint installs the endpoint (which depends on the sdk) so you get both

• We will try to use PEP420 (Implicit package namespaces) to have both the sdk and all the endpoint code in the same git repo, but separate pip installs.

• I believe this would look like:

  funcX/
    setup.py
    requirements.txt
    funcx/
        # no __init__.py
        sdk/
            __init__.py
            client.py
        endpoint_stuff/
            endpoint.py
            foo.py

  But I don't really know how this works, and I think it's not a super commonly used feature, so some experimentation is needed
