Create python requirements metadata (#1759)

- Create new metadata struct and type for python requirements.
- Update parsing of python requirements to use python requirements metadata.
- Remove extras and url from line. Add them to metadata instead.
- Add unit test to test that extras are removed from package name.
- Update test to look at requirements metadata.
- Will need updated in future to support more than just == for the version constraint.
- Update JSON schema data
