Add feedback endpoint to track quality of response

[aavetis]

Add the ability to hit an endpoint with any request ID to store whether the output was "positive" or "negative", allowing for live evaluation of interactions.

Consider..

• deploying a Functions app with bicep, getting the endpoint
• adding API spec to the APIM instance to handle the route
• pick a reliable request ID, and take a positive/negative parameter with it
• storage - store records in Cosmos? Azure Data Explorer? need a decision here
