Holger Weiss 8d5025076f PubSub: Add delete_old_pubsub_items command
Add a command for keeping only the specified number of items on each
node and removing all older items.  This might be especially useful if
nodes may be configured to have no 'max_items' limit.

Thanks to Ammonit Measurement GmbH for sponsoring this work.
