Let's discuss this in community meeting.
I would suggest drop support for older version at least until we release
Murano 1.0. As soon as we start to guarantee backward compatibility we will
introduce MinimalMuranoVersion instead of Version because format would not
change but some particular template may require feature that was introduced
after specified version.
