https://bugzilla.redhat.com/show_bug.cgi?id=1425757 The blockdev-add code provides a mechanism to sanely provide user and password-secret arguments for iscsi without placing them on the command line to be viewable by a 'ps -ef' type command or needing to create separate -iscsi devices for each disk/volume found. So modify the iSCSI command line building to check for the presence of the capability in order properly setup and use the domain master secret object to encrypt the password in a secret object and alter the parameters for the command line to utilize. Modify the xml2argvtest to exhibit the syntax for both disk and hostdev configurations.
