       Register a set of callbacks to receive Application Performance Monitoring events.

       The  callbacks  are  copied  by  the client and may be safely destroyed by the caller after this API call
       completes. If a context is passed, it is the application's responsibility to ensure context remains valid
       for the lifetime of the client.
