Subject: [PATCH] add notify-api-sms-callbacks app

we might need to deal with a potential large volume of SMS delivery
receipts. These receipts are POSTed to oru public api to two URLs. The
actual endpoint just parses the response body and puts a task on an SQS
queue - no database connections are required or anything like that.

Split up this traffic from other traffic, so that any increase in volume
of callbacks won't affect the scaling/load/etc of the main api apps.
We've hard coded instance counts to 10 on prod for now until we get an
idea of load.
