Refactor Client Managers
The current client managers instantiate all possible clients at __init__ time and expose the clients via class attributes.
The problem with this is that regardlless of tempest configuration about available services, extensions and API versions, all clients are instantiated.
The proposed change is: clients are only instantiated on demand, the manager internally caches instances of clients and serve them from cache where applicable, test base classes would use get_x_client instead of the attribute, and pass client specific parameters (i.e. API version, extension) into that call
