fix(kafka): Use wait strategy instead of deprecated wait_for_logs (#903)

Related to
https://github.com/testcontainers/testcontainers-python/issues/874.

Since those containers first need to be started to know their exposed
ports, we cannot use `DockerContainer._wait_strategy`. We have to keep
checking logs manually in their own `start` methods.

Let me know if there is anything to change.
