[REQ] Add Api key auth to aspnet core server package

Created by: MBcom

Is your feature request related to a problem? Please describe.

• on generating the aspnetcore server package - (bearer) authentication are ignored and roles/scopes specfied for each operation are ignored too
• it would be time saving if the generator would generate the missing annotations

Describe the solution you'd like

• if there is an api key authentication specified then annotate with [Authorize(Rules= "...")]
• add an IAuthorizationRequirement handler class
• and add the needed handler to Startup.cs file

Describe alternatives you've considered
