Add --range-type option that forces range type of the trusted domain
    
    Adds --range-type option to ipa trust-add command. It takes two
    allowed values: 'ipa-ad-trust-posix' and 'ipa-ad-trust'.
    
    When --range-type option is not specified, the range type should be
    determined by ID range discovery.
