2.11. OpenStack Integration Test Suite Service

This update includes an overall tempest cleanup including remote client debuggability, documentation review, client and manager aliases, and refactored test base class setup and teardown steps.

This update adds a domain-specific tempest run command that can be used as the primary entry point for running tempest tests.

While the existing negative tests remain, this update adds support to the negative tests at the component level.

With this update, the tempest-lib Python repository is now migrated to the tempest/lib directory in the tempest repository.

Previously, the client managers instantiated all available clients at _init_ time regardless of the `tempest` configuration about the available services, extensions and API versions and exposed the clients using the class attributes. With this release, clients are only instantiated on demand, and the manager internally caches instances of clients and serves them from the cache where applicable.

With this release, all test resources are managed in a dedicated YAML file, which allows for the tempest configuration to happen with the same amount of configuration a deployer system uses to configure the OpenStack services. This also ensures that the test can select resources to be used by the logical name or properties (for example, use whatever image that would fit in the 'smallest' flavor), or run against all combinations of certain resources.

This release adds some Compute Microversion tests to the Microversion testing framework.
