Right now we have a ping endpoint, but we need a health check as well.
what we could check in this health check are the state of the
database, send a ping to the push networks. And then send a response
accordingly 'critical' if the database is not up, 'warn' if one of the
networks is not responding and 'ok' if everything is fine. I've
created a issue for it https://issues.jboss.org/browse/AGPUSH-1347
