    Validate target host by scheduler
    
    In the current implementation, when we boot a server we can
    provide additional placement information through the scheduler
    hints mechanism. However, when we live migrate a server those
    scheduler hints are not taken into account.
    
    This patch adds the ability to check if the target host passes
    filters before live migration. To achieve that task those
    hints are persisted as a json blob into the database.
    
    This additional verification can leave the system locked, for
    instance two hosts which run servers that must be located on
    different hosts can't be migrated. Thus, an option
    'no-check-by-scheduler' has been set up in order to make this
    verification optional.
