test(node): Add mysql2 auto instrumentation test for @sentry/node-experimental

[timfish]

This PR adds a test for mysql2 auto instrumentation for @sentry/node-experimental.

mysql2 will not query unless there is a connection and it does not want to work without one like mysql.

This PR adds a withDockerCompose method to the test runner which handles:

• Starting the docker container
• Waiting until some specific output has been seen from the container so we know the server is up
• Closing and cleaning up the docker container/volumes

 createRunner(__dirname, 'scenario.js')
      .withDockerCompose({ workingDirectory: [__dirname], readyMatches: ['port: 3306'] })
      .expect({ transaction: EXPECTED_TRANSACTION })
      .start(done);

My only minor concern is that the mysql docker container creates a volume to store data. If the cleanup code does not run, a 180MB volume is left behind after every run. This will only be an issue when testing locally but we could start to fill developers machines. These can be cleaned up via docker volume prune --force but I would not want to run this on peoples machines without telling them!

Is there a way to auto clean the docker stuff? Or at least to add it to yarn clean for node-integration-tests to remove all of the ones we added, or something like this? 🤔

yarn clean will now force cleanup of the docker container and volumes
