Once T162576 and https://github.com/wikimedia/restbase/pull/796 are done (and other related patches too), update CX config to use new Restbase provided public API instead of CXServer.
Timeline:
- Add configuration patch for CX and update documentation.
- Update CX Labs instances.
- Deploy in Beta.
- Deploy in Production.
- Deprecate: cxserver.wikimedia.org URL
Issues:
- Deploy: CXServer's /list/{tool}{/from}{/to} should work when only {from} is provided
