    Raise error when running ipa-adtrust-install with empty netbios--name
    
    When running ipa-adtrust-install, a netbios-name option must be specified.
    Currently if an invalid netbios name in form of empty string is specified, the
    installation proceeds, but changes the invalid value to a netbios name
    determined from domain name without any notification.
    
    Fixing this so that any attempt to supply empty string as netbios name fails
    with error in case of unattended installation, or to request input of valid
    netbios name from command line during normal installation.
