Low: attrd: broadcast local overrides of sync'ed attributes
    
    In the case of an attribute that was set on a stopped node, when the node
    rejoins, the peer writer will sync its attributes including that value. The
    node will reject it, overriding it with the local value (empty string).
    
    Previously, it would send that override only to the peer writer, meaning that
    any other nodes would still have the previous value in memory (and would
    respond to queries with it). Now, the node broadcasts any local overrides,
    so that all nodes get the correct value.
