Add a functional vm_test for root_test.

This change renames the tools/images directory to tools/vm for clarity, and
adds a functional vm_test. Sharding is also added to the same test, and some
documentation added around key flags & variables to describe how they work.

Subsequent changes will add vm_tests for other cases, such as the runtime tests.
