While working on apache/accumulo-fluo#1055 I found it cumbersome to configure Fluo and Accumulo to dispatch Fluo notification scans to a dedicated executor. With these changes its much simpler to do that. Fluo can set an execution hint like `scan_type=fluo-ntfy` and Accumulo can be configured to execute the scan based on the type without changing Fluo config or source code. Before these changes, Fluo would have required either a custom dispatcher or custom Fluo config for Accumulo executors. With these changes nothing needs to be done in Fluo.

You should also update the website (if needed): https://accumulo.apache.org/docs/2.x/administration/scan-executors
