Tests that get killed do not have an opportunity to clean up. There are many bad states this can leave the system in, but of particular gravity is when zinject has been used to induce bad behavior for one or more of the test disks. Create a failsafe mechanism in test-runner.py that runs a callback script after every test. The script is common to all tests so all tests benefit from the protection. Add an obligatory `zinject -c all` to clear all zinject state after every test case is run.
