Adding support for payload multiple-stream.

The multiple-stream effort will contain multiple images considered as
`machine-os` in the payload as well as multiple `driver-toolkit` images.

This commit is adding some labels to the container such as the
`rhel-stream` and `kernel-version`.

In addition it adds a reference to the `rhel-coreos-10` image in order to
specify to the payload that DTK depends on the `rhel-coreos-10` image.
