    API extension for instance migration history
    
    Adds a new API extenstion to access migration history
    information for given instance.
    
    Admins are frequently in need to access migration related
    data and the only way to do this right now is to go to the
    db. This extension attempts to solve that by providing a simple
    way to list migration history for a given instance.
    
    Implements blueprint bp-migration-history-ext
