Match batch size to payload limit in bytes for AWS

[derekedmondflutter]

What would you like to be added:
The ability to configure aws-batch-change-size so that it can be set to the max number of bytes AWS accept rather than the number of records.

Why is this needed:
The AWS limit on batches is a payload limit in bytes - 32000 (at time of writing). This doesn't match up with aws-batch-change-size which is the number of records. During scaling events, there can often be issues when the AWS R53 limit is reached. The most common scenario where this fails, is when we have a batch of 1000 records, but the names are much longer than usual (in the case of test events).

It would be great if external-dns could understand the size of the payload it is about to send and then shape the payload to be under the limit AWS have set- 32000 (at time of writing).
