In Python 3, `print` is no longer a statement. Call it as a function
everywhere, and include the future import to remove the statement
in Python 2 code as well.

The 'as' syntax works from Python 2 on, and Python 3 will
drop the "comma" syntax.

The racker object "remembers" expected state across several tests,
so only changes (rather than all expected state) need to be specified
in each test. Also, the tracker fixture will make it easy to use hosts
in other test modules.

This change makes the tests independent; any permutation of any subset
of these tests should now pass.

This has several advantages:
- Tests other than run-command/check-response can be added easily
- Tracebacks are meaningful (which means we'll be able to remove a lot of
  test name/description/location tracking code)
- Individual tests can be selected/deselected using normal pytest mechanisms
  (but for isolated tests, more changes will be needed)
