Release designateclient and solumclient be able to uncap jsonschema

We have jsonschema capped at a fairly old version. Other than some
    specific releases, it looks like keeping it below 3.0 was added in
    I943fd68b9fab3bce1764305a5058df5339470757 without really any explanation
    why.

    In order to update to a 3.x release we need to:
    1. Remove the cap from global-requirements.txt, leaving
       upper-constraints.txt at a 2.x release
    2. Remove the cap from all consumers
    3. Release a new version of consumers that are published to pypi (this change)
    4. Update upper-constraints.txt with those new releases

This review perfoms step 3.
