Deprecate StrimziKafkaContainer

[see-quick]

This PR initiates the migration of the Strimzi Kafka Container API. The plan is to remove this class from the public API in' 0.114.0' and enforce the use of StrimziKafkaCluster for all users. Strimzi Kafka Container will still be used internally (as encapsulation of most logic within the container).

Users could easily change their testing envs by following:

StrimziKafkaContainer systemUnderTest = new StrimziKafkaContainer()
systemUnderTest.start();

with

StrimziKafkaCluster systemUnderTest = new StrimziKafkaCluster.StrimziKafkaClusterBuilder()
       .withNumberOfBrokers(1)
       .build();
systemUnderTest.start();
