Managed Identity support for Azure bot services

[deramamo]

Issue

Overhead of maintaining Bot service credentials and renewing client secret to access bot services deployed in global azure resource

Proposed change

Provide Managed Identity support for azure bot service

Component Impact

Azure Bot Service

Customer Impact

When secrets are about to expire in production Bot services, we are having to alert on the secret expiration and renew the secrets every 6 months. If a dev overlooks the alerts, or n expiration date is not set on the secret and misses the time to rotate secret, the bot deployed in that region fails to respond and our Customers are unable to get to our bot..
