fix(kinesis): set required dimensions for Firehose quota metrics (#378)

According to AWS Docs [here](https://docs.aws.amazon.com/firehose/latest/dev/monitoring-with-cloudwatch-metrics.html), all firehose metrics require 'DeliveryStreamName' for filtering, this include Bytes, Records and PutRequest Per Second Limit metrics.

Fixes bug where firehose quota limits metrics not working.
