Add Cloud Role Name to Live Metrics Stream
On the Live Metrics Stream, the list of servers is displayed.
1. Allow to list a column called 'cloud role name' next to the server name. This makes it clear which server correlates with which server.
2. Allow easy filtering of the entire page by 'cloud role name'.
When multiple roles share a single application insights resource, it an be hard to figure out which server is doing what. Still, it makes sense to log in a single app insights resource in order to have the relation and querying benifits.
