Add option to specify SID using domain name to idrange-add/mod
    
    When adding/modifying an ID range for a trusted domain, the newly
    added option --dom-name can be used. This looks up SID of the
    trusted domain in LDAP and therefore the user is not required
    to write it down in CLI. If the lookup fails, error message
    asking the user to specify the SID manually is shown.
