title: GoogleApiClient seems to have no callback for the disconnect() API...?
body: <p>If you invoke GoogleApiClient #connect() you are not actually connected until the onConnected callback handler is invoked.</p>
  
  <p>However, it seems no such "notification" is given for the #disconnect() API call. Am I missing something, or perhaps disconnects are assumed to occur immediately, hence no callback?</p>
  
  <p>I do see an #onConnectionSuspended callback but it doesn't seem to be invoked when you disonnect(), probably is for more exceptional situations.</p>
  
  <p>Thanks for your help.</p>
