Send api.fault notification on API service faults.

Exceptions caught by the API middleware will now send "api.fault"
notifications indicating the offending URL and the underlying exception.
The allows the billing/usage systems to track requests end-to-end without
having to monitor log files. Disabled by default.
Enable with --notify_api_faults
