A connection to the Cloud Spanner instance administration service.
This interface defines pure-virtual methods for each of the user-facing overload sets in InstanceAdminClient. This allows users to inject custom behavior (e.g., with a Google Mock object) in a InstanceAdminClient object for use in their own tests.
To create a concrete instance that connects you to a real Cloud Spanner instance administration service, see MakeInstanceAdminConnection().
