Support multi-application scenarios

[kendaleiv]

Today, Stuntman can load users from paths and urls by virtue of AddUsersFromJson(string).

However, we want to support the notion of a client/server relationship, where the client requests the users that are configured in the server.

• The server will need to expose the users via a special endpoint
• The client can request these users to add to the list of users, or make a request for the access token or other information for a particular user.
  • We may want to support both mandatory and optional scenarios in terms of the server responding successfully.
