1. Get rid of fixed ROOT, *_BUNDLE, and CONSOLE_SOCKET dirs. Now they are temporary directories created in setup_bundle. 2. Automate containers cleanup: instead of having to specify all containers to be removed, list and destroy everything (which is now possible since every test case has its own unique root). 3. Randomize cgroup paths so two tests running in parallel won't use the same cgroup. Now it's theoretically possible to execute tests in parallel. Practically it's not possible yet because bats uses GNU parallel, which do not provide a terminal for whatever it executes, and many runc tests (all those that run containers with terminal: true) needs a tty. This may possibly be addressed later. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
