I think it'll also make sense to limit the config setting
`ConsumerConfigConstants.SHARD_GETRECORDS_INTERVAL_MILLIS` to be lower than the
shard iterator expire time, otherwise the shard iterator will definitely
timeout on the next `getRecords()`.
AWS documentation says the expire is 5 minutes
(http://docs.aws.amazon.com/kinesis/latest/APIReference/API_GetShardIterator.html),
I propose to set the limit to be 4.5 min, although I don't expect any user
would actually set such a high value.
Adding this now...
