satori: Drop requirements, pypi, and old upstream

- Satori is a stackforge project, so we don't need
the requirements gates. We're also experimenting
with additional checks and those gates block us.
- We manage pypi releases manually there are no
other projects that use Satori through pypi yet. 
- The old upstream is going to be deleted.
