    KAFKA-4588: Wait for topics to be created in QueryableStateIntegrationTest.shouldNotMakeStoreAvailableUntilAllStoresAvailable

    After debugging this i can see the times that it fails there is a race between when the topic is actually created/ready on the broker and when the assignment happens. When it fails `StreamPartitionAssignor.assign(..)` gets called with a `Cluster` with no topics. Hence the test hangs as no tasks get assigned. To fix this I added a `waitForTopics` method to `EmbeddedKafkaCluster`. This will wait until the topics have been created.
