New releases of oslo.config support a 'mutable' parameter to Opts. Configuration options are mutable if their oslo.config Opt's mutable=True is set. This mutable setting is respected when the oslo method mutate_config_files is called instead of reload_config_files. Icec3e664f3fe72614e373b2938e8dee53cf8bc5e allows services to tell oslo.service they want mutate_config_files to be called by specifying the 'restart_method=mutate' parameter, what this patch does. The default mutable configuration options (set by oslo.config Opts' mutable=True) are: - [DEFAULT]/pin_release_version - [DEFAULT]/debug - [DEFAULT]/log_config_append Concrete params, that made mutable in Watcher: * watcher_decision_engine.action_plan_expiry * watcher_decision_engine.check_periodic_interval * watcher_decision_engine.continuous_audit_interval * gnocchi_client.query_max_retries * gnocchi_client.query_timeout * DEFAULT.periodic_interval Change-Id: If28f2de094d99471a3ab756c947e29ae3d8a28a2 Implements: bp mutable-config
