--- features: - The Tempest plugin interface contains a new optional method, which allows plugins to declare and automatically register any service client defined in the plugin. - tempest.lib exposes a new stable interface, the clients module and ServiceClients class, which provides a convenient way for plugin tests to access service clients defined in Tempest as well as service clients defined in all loaded plugins. The new ServiceClients class only exposes for now the service clients which are in tempest.lib, i.e. compute, network and image. The remaining service clients (identity, volume and object-storage) will be added in future updates. deprecations: - The new clients module provides a stable alternative to tempest classes manager.Manager and clients.Manager. manager.Manager only exists now to smoothen the transition of plugins to the new interface, but it will be removed shortly without further notice.
