Push Gateway API
================
Clients may want to receive push notifications when events are received at
the homeserver. This is managed by a distinct entity called the Push Gateway.

provider (e.g. APNS, GCM).

Homeserver behaviour
--------------------
This describes the format used by "HTTP" pushers to send notifications of
events to Push Gateways. If the endpoint returns an HTTP error code, the
homeserver SHOULD retry for a reasonable amount of time using exponential backoff.
