Fix hw_settle and disk update during upgrade

Browse Source 
This update addresses an issue with the hw_settle
and disk update during an upgrade. Previously,
the hw_settle parameter was only being updated for
controllers, this fix extends the update
to all hosts. This change the prefix on
wwn-* paths. The default for ISCSI devices
is 3, for virtualized envs like QEMU
might not start with 3.

Test plan:

PASS: Upgrade Standard 2+2+2 with multipath (QEMU)
