Openownership work needed

[ghost]

There are several things happening here:

1. Remove the code that disabled get_remote_json. Now I'm not entirely sure why this was disabled in the first place - maybe just enabling it again will cause other issues?

2. Pass base_uri to jsonref.load - this is needed or it can't load relative files.

3. Remove Python 2 support. If we really want this, then I've added pathlib.Path which is 3 only.

Discussed with @kindly on call but now put as PR for all to discuss.

This is related to openownership/data-standard-sphinx-theme#4

Yes this causes issues. For open contracting we have a URI for each of the schema files, which sometimes doesn't yet have a schema at it (e.g. after we increment the URI, but after we have a build to copy to the relevant locations) - here's an example https://github.com/open-contracting/standard/compare/example-1__1__4-bump
I'm aware that maybe isn't very clear, so happy to have a quick call.

Closing. This still needs to be looked at, but must be done in a different way.
