A connection to Cloud Pub/Sub for subscription-related administrative operations.
This interface defines pure-virtual functions for each of the user-facing overload sets in SubscriptionAdminClient. That is, all of SubscriptionAdminClient overloads will forward to the one pure-virtual function declared in this interface. This allows users to inject custom behavior (e.g., with a Google Mock object) in a SubscriptionAdminClient object for use in their own tests.
Applications may define classes derived from SubscriptionAdminConnection, for example, because they want to mock the class. To avoid breaking all such derived classes when we change the number or type of the arguments to the member functions we define lightweight structures to pass the arguments.
