Release 1.8.5 of the Amazon Kinesis Client for Java (#232)

* Release 1.8.5 of the Amazon Kinesis Client for Java

Release 1.8.5 (September 26, 2017)
* Only advance the shard iterator for the accepted response.  
  This fixes a race condition in the `KinesisDataFetcher` when it's being used to make asynchronous requests.  The shard iterator is now only advanced when the retriever calls `DataFetcherResult#accept()`.
  * PR #230
  * Issue #231

To make it easier for developers to write record processors in other languages, we have implemented a Java based daemon, called MultiLangDaemon that does all the heavy lifting. Our approach has the daemon spawn a sub-process, which in turn runs the record processor, which can be written in any language. The MultiLangDaemon process and the record processor sub-process communicate with each other over [STDIN and STDOUT using a defined protocol][multi-lang-protocol]. There will be a one to one correspondence amongst record processors, child processes, and shards. For Python developers specifically, we have abstracted these implementation details away and [expose an interface][kclpy] that enables you to focus on writing record processing logic in Python. This approach enables KCL to be language agnostic, while providing identical features and similar parallel processing model across all languages.
## Release Notes
### Release 1.8.5 (September 26, 2017)
* Only advance the shard iterator for the accepted response.
This fixes a race condition in the `KinesisDataFetcher` when it's being used to make asynchronous requests. The shard iterator is now only advanced when the retriever calls `DataFetcherResult#accept()`.
* [PR #230](https://github.com/awslabs/amazon-kinesis-client/pull/230)
* [Issue #231](https://github.com/awslabs/amazon-kinesis-client/issues/231)
### Release 1.8.4 (September 22, 2017)
* Create a new completion service for each request.
This ensures that canceled tasks are discarded. This will prevent a cancellation exception causing issues processing records.
