Suggestion: add an example of how to make requests to the deployed AKS service

[mx-iao]

A customer had an issue with trying to make a request to the deployed AKS service from this example: https://github.com/microsoft/MLOpsPython/blob/master/diabetes_regression/scoring/deployment_config_aks.yml

The issue was with the web service authentication - they weren't sure how to access the authentication key for the service. Additional example or pointer to documentation (e.g. this) could help prevent future confusion.

Can I work on this issue ?
