Config: Flag config uidgid entries
    
    Uidgid entries parsed from configuration files now has prefix
    (uidgid.config.) so they are distinguishable from dynamically added
    entries. Entries added from config file are pruned on reload if no
    longer exists in config file (dynamic one stays unaffected). Also whole
    uidgid.config. prefix is made read only.
    
    This make PCMK work again after configuration reload is called.
