Currently calling this code blows up if using an older ramdisk. If
default values for 'portal_port' or 'wipe_disk_metadata' parameters
are set, do not pass it to IPA to workaround this problem. If
start_iscsi_target fails and wipe_disk_metadata is True, try to
start iSCSI without it, if custom portal_port is requested, tell the
user that either ramdisk should be updated or default port should be
used.
