TIDM onap.nodes.Container

Nodes of this type represent a virtualization container, such as a VM or a Docker container.

Used to express advanced VNFC deployment scenarios, such as:

Multiple VDUs sharing a container and its hardware resources
Stacking software images

Since AbstractCompute is an abstract type, we cannot provide a deployment image artifact to initialize it (this will turn it into a concrete type, will inverse the capabilities and confuse the orchestrator). Instead, we can use a Container (or even a stack of containers) with the initialization images to use.

TODO: update the type definition with a required deployment artifact, to ensure that nodes of this type are always concrete
