[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

```
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
