SD-365 : Spike: Research async notifications

Spike: Research async notifications

A testing draft for notification on the client media-archive.
The query looks like this:
{"where": {"_created": {"$gte": last}}};
so probably because of the "$gte" is not sending this data so in the actual request looks like this:
?where={"_created":{}},
basically escaping and JSON string provides the proper query, I don't think this is the problem.
