FEATURE: Python SDK added. Can be found on [pypi](https://test.pypi.org/project/zrok-sdk). `pastebin` example illustrates basic SDK usage (see `sdk/python/examples/README.md` for details) (https://github.com/openziti/zrok/issues/401)
CHANGE: Moved the golang zrok sdk into `sdk/golang/sdk` to normalize location for future SDK's.
CHANGE: add restart policies to docker compose samples used by the guide docs, e.g., reserved public share should auto-start on boot, temp public share should not.
