Issue description and reproduction steps

The error response for cloud shell is different and needs to be handled differently to get the error message.

Currently for managed identity error response we only look at the top level for error message and error response. For cloud shell the error message is one level down in the json.

Sample error response from cloud shell when a wrong scope is passed.
