Explore using Provisio and JIB to make a highly optimized Docker image

Provisio knows the exact set of items that go into a runtime so it would be possible to feed that information into JIB to make a highly optimized Docker image.

NOTE: @briandealwis mentioned that JIB currently doesn't support hardlinks, but we can look at adding that support when we get there.
