[PATCH 3/4] classes: allow more control over container image name and tag

[Henning Schild <henning.schild@siemens.com>]

This patch allows more fine-grained control over how the resulting
container will be tagged. Where the default name will be PN together
with DISTRO and ARCH, and tag will be derived from PV and PR
