        Deletes the data and the container itself for the given container. This
        will call :func:`reap_object` up to sqrt(self.concurrency) times
        concurrently for the objects in the container.

        If there is any exception while deleting a single object, the process
        will continue for any other objects in the container and the failed
        objects will be tried again the next time this function is called with
        the same parameters.

        If there is any exception while listing the objects for deletion, the
        process will stop (but will obviously be tried again the next time this
        function is called with the same parameters). This is a possibility
        since the listing comes from querying just the primary remote container
        server.

        Once all objects have been attempted to be deleted, the container
        itself will be attempted to be deleted by sending a delete request to
        all container nodes. The format of the delete request is such that each
        container server will update a corresponding account server, removing
        the container from the account's listing.

        This function returns nothing and should raise no exception but only
        update various self.stats_* values for what occurs.

        :param account: The name of the account for the container.
        :param account_partition: The partition for the account on the account

        :param account_nodes: The primary node dicts for the account.
        :param container: The name of the container to delete.
