dispatch _configure_aparams in PlatformAgent so the alert definitions are captured and processed. UI testing OK as well as all unit and selected relevant integration tests.
adjust existing test_alerts in test_platform_agent_with_rsn.py so not only the alerts defined via set_agent are tested, but also alerts that are defined and passed via configuration.
fix missing import of IonObject
log a warning in _restore_resource (not implemented yet)
skip test (not ready yet)
