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.
