Docker-Compose support

With this release, you can now use docker-compose files to run your tests. See this feature in action at examples/03-docker-compose. Thanks @jpulec for this contribution.

no restarts in watch mode

With this release; jest-testcontainers will not restart containers in watch mode. Meaning you will have one instance of your containers that you will use throughout re-runs of your test. Giving you a huge performance boost 🎉

This release breaks backward compatibility because there maybe integration tests written that expect containers to be restarted. E.g. your tests may modify the database. With the previous versions, these changes would perish when the tests restart because containers would be re-created.

To continue with the old behaviour, you can set JEST_TESTCONTAINERS_RESTART_ON_WATCH env variable to a non-empty string.
Or refactor your tests to clean up after themselves, so re-runs of your tests won't affect eachother.

add ryuk container reaper

started to use a later version of testcontainers-node that support reaping of containers in case test process fail unexpectedly. this means no more zombie containers.
