Release v1.1.3

• (@GermanBluefox) Added the quiet option to DockerManager: a manager created only to probe whether Docker is available now reports its absence on debug level instead of warn/error, so a pure availability check does not fill the log of an adapter that runs no container
• (@GermanBluefox) The failed probe of /var/run/docker.sock no longer goes to the console, but into the debug log of the adapter - it is a normal outcome on a host that uses the CLI, TCP, or has no Docker
