Monty Taylor 650392c700 Start making 3.8 python images
base and builder are currently pinned to 3.7, which makes it hard
to consider upgrading to python-3.8. To help with that, make
python-3.7 and python-3.8 images, but point latest as 3.7 for the
time being. Then add version-specific provides and FROM lines
so that we can start being deliberate and clear about our version
choice.
