Fix: agents: handle dampening parameter consistently and correctly

Always quote variable when used (in case value incorrectly contains whitespace), always use attrd_updater -B instead of -U to ensure dampening is truly reloadable, and always mark parameter as reloadable in metadata. Also, dampening doesn't need to be passed with attrd_updater -D.
