+Kill tasks delete all information about a segment and removes it from deep
storage. Segments to kill must be unused (used==0) in the Druid segment table.
+
+The available grammar is:
```json
{
"type": "kill",
"id": <task_id>,
"dataSource": <task_datasource>,
"interval" : <all_segments_in_this_interval_will_die!>,
+ "markAsUnused": <true|false>,
"context": <task context>
}
```
+If `markAsUnused` is true, the kill task will first mark any segments within
the specified interval as unused, before deleting the unused segments within
the interval.
