boot: Implement DELETE method.

  * Add a more complex DELETE method that accepts either an ID
    or a query to specify which boot reports to delete. This is
    specific only to the boot handler.
  * Refactor the base handler and created a new method to retrieve
    the date_range query. This is necesary to limit the boot delete
    method to not include date range deletion.
  * Add boot handler test focused on the DELETE implementation.
