* Single universal ClientManager class was dropped in favor of of individual in-context methods to create OS clients without ClientManager restrictions. * Environment class was renamed to ExecutionSession to avoid common confusion with io.murano.Environment * execution_session_local module was introduced to simplify keep of per-execution session (per-deployment) data. This is similar to thread-locals with the difference that there can be many threads in single session. * All OS-clients related code was migrated to keystone client sessions and API v3 (except for GLARE and Mistral that doesn't support sessions). This increases performance and solves authentication problems that could be caused by token expiration even with trusts enabled. * [DEFAULT]/home_region setting was introduced instead of [murano]/region_for_services to configure what region should be used by the clients by default (where Murano API resides). All client factories respect this setting. Change-Id: If02c7e5d7d39574d0621e0e8dc27d1f501a31984
