[DOCS] Clarify is_metal is required if using iSCSI

Browse Source 
When using a storage backend which depends on the iSCSI protocol, such
as a NetApp or VNX appliance in iSCSI mode, cinder would work only
partially. New volumes could be created, but download to image and
backup routines would not work, and the reason would not be clear from
the logs.

# When using lvm as a cinder backend its advised to run cinder-volumes on metal.
# When using LVM or any iSCSI based (see LP#1226855) cinder backends, such as
# NetApp with iSCSI protocol, it is advised to run cinder-volumes on metal.
# If you are using a different backend you may want to remove "is_metal: true".
# Otherwise if cinder-volumes is already running in containers you may want to
# leave is_metal off, alternatively you will have to migrate your volumes once
