Integration services improvements

[hikalkan]

Improvements based on #12896:

• Allow to use [IntegrationService] attribute on application service interfaces, in addition to the class. Defining on the interface is the preferred way when the service has interface. In this way, clients (those has access to the interface) can know about it.
• Allow to filter service types while creating conventional controllers
• Allow to filter service types while creating dynamic / static client proxies
