multiple endpoints on services

[aricart]

Overview

The ADR for service api has been modified to:

• Allow for multiple endpoints via AddEndpoint(name, handler?, subject?)
• Allow grouping of endpoints via AddGroup(subject)
• Info responses return a list of all the user subjects the service is listening on
• Stat responses are not per endpoint.

Please check the ADR for more information.
