Introduce testcontainers for integration tests

`testcontainers` replaces `boltkit` as library to start docker containers.

The container should be able to start when `npm run test`, `npm run test::integration` and `npm run test::browser` are run if methods are not called from testkit.

Running the tests direct from the IDE should be also an supported usecase.
