Replace portBindings.add with standard way of exposing ports

How to expose ports:

portBindings.add("$externalPort:$internalPort")

Unfortunately container.getMappedPort() works only after starting containers. Test classes logic relies on fetching the port number before starting container, so in my opinion current implementation is justified.

I think @slonka had in mind using .withExposedPorts(8080, 8081) instead of portBindings.add("$externalPort:$internalPort")
