container tag discover needs to support multiple labels to build tag

[Steve Baker]

Some downstream build pipelines do not apply a label which exactly matches the version tag. The only way to build the full versioned tag is by combining multiple labels in a template pattern.

If --tag-from-label could take a template pattern which contains multiple labels, these build pipelines can be accommodated.

    Allow a combination of labels for tag discover

    Some downstream build pipelines do not apply a label which exactly
    matches the version tag. The only way to build the full versioned tag
    is by combining multiple labels in a template pattern.

    This change uses a python string.format syntax to allow multiple tags
    to be combined.

Reason: Gate resets is causing issue to land a critical patch (538346) - I need to clear the gate until 538346 is merged. Please do not restore this patch, I'll take care of it.

I'm reopening this because there is a fix required for the tags to be actually substituted in the resulting file.
