KAFKA-4687: Fix InvalidTopicException due to topic creation race condition
Pull request for https://issues.apache.org/jira/browse/KAFKA-4687, complete
details can be found in the Jira.
With this change, instead of incorrectly throwing an InvalidTopicException,
a TopicExistsException would be thrown
[here](https://github.com/apache/kafka/blob/0.10.1.1/core/src/main/scala/kafka/admin/AdminUtils.scala#L474).
Note that an alternative (or possibly additional) change could be to
proactively check if the retrieved topic inventory
[here](https://github.com/apache/kafka/blob/0.10.1.1/core/src/main/scala/kafka/admin/AdminUtils.scala#L432)
contains the topic being created, and throw a TopicExistsException at that
point. Let me know if that would be preferred, and I'll update the code
accordingly.
