autorun/lio_local: preload the loop kernel module
79d99b8 
This is a workaround for us not yet pre-populating /dev with kmod
static-nodes during early init, which means losetup /dev/loop-control
access doesn't trigger module load.

Use modprobe -a to load multiple modules in one call and drop explicit
mention of the target_core_mod dependency.

autorun: add CHAP support to lio-local and openiscsi images
e9c6ed9 
Add new ISCSI[_MUTUAL]_USER and ISCSI[_MUTUAL]_PASS configuration
options, which when set trigger CHAP configuration on the lio-local and
openiscsi images.

autorun/lio_local: disable demo_mode_write_protect
9c6cb23 
We're currently setting prod_mode_write_protect=0 and
demo_mode_write_protect=1. This used to not result write-protection for
exposed LUNs, but that appears to now be the case. Set
demo_mode_write_protect=0 to account for this upstream change in
behaviour.

autorun/openiscsi: create /run/lock/
32ed141 
openiscsi fails if it can't create a file under /run/lock/, so create
it. This is likely a regression with the move to rapido-init, where
dracut init created the directory.

libiscsi_test_tool: cut and autorun scripts
8454580 
The libiscsi test-tool is useful for testing SCSI and iSCSI storage
protocols.
