    vos: Minimize release impact for new RO sites
    
    Currently, if a new RO site is added with 'vos addsite', the only way
    to populate the new site with data is a 'vos release' (excepting hacks
    using 'vos restore' and 'vos addsite -live', etc). Due to safeguards
    in 'vos' ensuring that RO sites always all contain the same data when
    marked as up-to-date in the VLDB, such a release always incurs some
    amount of data to be transmitted to all sites, as well as remote sites
    being brought offline briefly, even when the RW data has not changed
    in very long time.
    
    To alleviate this situation, make 'vos release' detect if new,
    unpopulated RO sites have been added, and if the RW volume has not
    changed since the release of any existing RO sites. If both of these
    conditions are true, do not update any of the existing sites, but only
    transmit volume data to the sites that did not already contain RO
    volumes.
