Falcon 2.0.0 introduces some breaking changes. The relevant ones here are: - falcon.testing.TestCase.api property was removed - falcon.testing.TestBase class was removed Additionally, the default behaviour for handling trailing slashes on URIs also changed: https://falcon.readthedocs.io/en/latest/user/faq.html#how-does-falcon- handle-a-trailing-slash-in-the-request-path This commit adds support for using the new release. It currently makes no effort to be backwards compatible with older releases. The change also updates the requirements for influxdb and sphinx libraries to match global requirements. Until monasca-log-api implementation is not updated to support the new version of Falcon, `monascalog-python3-tempest` is marked to be non-voting as agreed in the team meeting.
