Operating-system-level virtualization (OSLV) discovery

Discovery can collect image and container information from OSLV engines.

Discovery can determine container status and size and identify images and their tags provided by operating-system-level virtualization.

Note: Currently, the ServiceNow® platform supports the discovery of Docker virtualization containers only.
