aws/request: Add LimitExceededException throttled exception for Kinesis

[pdalinis]

Kinesis returns LimitExceededException when the rate limit is hit. This PR adds this exception to the list of throttled exceptions.

Thanks for taking the time to create this PR @pdalinis. I think the idea of this change is good, but I don't think we can accept this change as in. Specifically because the LimitExceededException is a common exception returned by multiple services with different meanings.

This exception was originally in the SDK but removed in #1276 because it was found to conflict with DynamoDB's usage of this same exception code. Later another issue, #1376 was raised with the SDK about not retrying the LimitExceededException in Kinesis as well.

I think if the SDK were to retry this exception we need to take a deeper look at how the SDK chooses to retry exceptions. Potentially updating the SDK to apply some retry behavior to specific API operations or services. e.g LimitExceededException would be retried for Kinesis but not DynamoDB. This SDK does not currently have this behavior.

Lets track this discussion and design in, #1376.

Thanks for taking to time to create this PR, but lets use the #1376 item to track how the SDK could implement service specific retry behavior. Closing this PR in favor of that issue.
