Fix Hot Reloading

[pattisdr]

Purpose

Fix hot reloading again, while making sure the solution doesn't cause importlib.metadata.PackageNotFoundError: fidesops. A fix to one can break the other and vice versa.

While we improved hot reloading recently, #18, a separate fix to build the python package for fidesops on a fresh install #48 broke hot reloading again (it looks like watchgod is working, but it's deceptive, the actual file changes aren't reloaded).

Changes

• Whitelist the .egg-info directory to keep the copy of fidesops on the host machine from overriding it, so when we do make server we can find the fidesops package.
• Revert Dockerfile to make the WORKDIR be '/fidesops` before building the python package for fidesops, which we seem to need for reloading.

To test

• On a completely fresh install run make server and make sure 1) fidesops gets installed properly and 2) hit an API endpoint, make a change to that endpoint and hit the endpoint again and make sure the actual file changes were reloaded and are reflected in the response
