title: GCM "upgraded" to FCM
body: <p>It seems to no longer be possible to enable the gcm api for new apps. If I'm using parse-server as a BaaS which requires gcm to push notifications out on Android side and I can no longer do that because fcm breaks that implementation. What now? I believe this is Google's way of pushing developers off of parse-server and into the arms of Firebase. Is it in fact possible to use fcm with parse-server or am I going to have to use a different push provider and implement parse-server's pushadapter?</p>
