Provide a warning when a base image is unsupported

[baronfel]

Containers may support an OCI Annotation that is used to declare their support status. For example, soon Microsoft-produced images will support the vnd.microsoft.artifact.lifecycle.end-of-life.date annotation. The SDK Container tools should support warning a user when the base image used are building on is out of support. The behavior/annotation used should:

• vary based on the base image chosen until/unless there is some emergent standard here
• be explicitly set by the user
• be able to be disabled entirely by the user
