Added internal count metrics in addition to the external counts that are already there

[jakobht]

What changed? Added new metric which gives the max per workflow ID rps we have seen for the domain every second

Why? This will help users understand how close they are to the per workflow ID rate limits

How did you test it? Unit tests

Potential risks Just adding a metric, so should be safe
