Running the full test suite takes a long time. It would be useful to
distribute tests across multiple sandbox instances to speed up testing.
Add support for running tests in parallel across multiple sandbox
instances. Each worker runs a subset of tests based on its worker ID.
Add -P<n>:<w> option to the ut command where n is the total number of
workers and w is this worker's ID (0 to n-1). Tests are distributed
by index modulo number of workers.

test: Various improvements to unit-test infrastructure
This series adds several improvements to the unit-test infrastructure:
- Move disk images to the persistent-data directory so they don't
pollute the source tree
- Add a way to keep pytest-created artefacts for faster iteration on
C tests
- Add a helper to simplify running manual unit tests from Python
- Allow combined flags with the ut command (e.g. -Efm)
- Add a -E flag to emit machine-readable result lines
- Add a -P flag to distribute tests across parallel workers
- Add -m as an alias for -f (force manual tests)
These changes make it easier to run and debug tests, especially when
iterating on C test code.
