## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->


## How did you test it?
Tested it locally by ingesting some test data in authentications tables in CKH. 
CURL for /metrics/auth_events introduced two new fields   authentication_exemption_approved_count and authentication_exemption_requested_count here
