    [FLINK-7600][kinesis] shorten delay of KinesisProducerConfiguration.setCredentialsRefreshDelay() to avoid updateCredentials Exception

    ## What is the purpose of the change
    
    we saw the following warning in Flink log:
    
    ```
    2017-08-11 02:33:24,473 WARN  org.apache.flink.kinesis.shaded.com.amazonaws.services.kinesis.producer.Daemon  - Exception during updateCredentials
    java.lang.InterruptedException: sleep interrupted
    	at java.lang.Thread.sleep(Native Method)
    	at org.apache.flink.kinesis.shaded.com.amazonaws.services.kinesis.producer.Daemon$5.run(Daemon.java:316)
    	at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511)

    	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
    	at java.lang.Thread.run(Thread.java:748)
    ```
    
    According to discussion in https://github.com/awslabs/amazon-kinesis-producer/issues/10, setting the delay to 100 will fix this issue
    
    ## Brief change log
    
      - *shorten aws credentials refresh delay to 100 millisec*
    
    ## Verifying this change
    
    This change is a trivial rework / code cleanup without any test coverage.
    
    I've been running the fixed flink-connector-kinesis for a few days on AWS, and that warning log never happens again

    LGTM, thanks for the investigation.
    
    I would add a comment about the specific change though, otherwise it would be meaningless for other readers. Will add that when merging.
