This ensures that even if security scanner pagination sends Old and New layer IDs on different pages, they will properly be handled across the entire notification.

The FakeSecurityScanner mocks out all calls that Quay is expected to make to the security scanner API, and returns faked data that can be adjusted by the calling test case
With https://github.com/coreos/clair/pull/278 and https://github.com/coreos/clair/pull/279, performance of this API call has increased. It has been observed that querying 100 or 1000 layers page doesn't noticeably change the execution time. Therefore, doing significantly less calls will reduce the overall processing time for each notification.
Fixes#1301
- Ensures that the worker uses pagination properly
- Ensures that the worker handles failure as expected
- Moves marking the notification as read to after the worker processes it
- Increases the number of layers requested to 100
