Code Issues Proposed changes

Add mpath support to wipedisk script

Browse Source 
The wipedisk script was not able to find the boot device
when using multipath disks. This is due to the fact that
multipath devices are not listed under /dev/disk/by-path/.

To add support to multipath devices, the script should look
for the boot device under /dev/disk/by-id/ as well.

Test Plan
PASS: Successfully run wipedisk on a AIO-SX with multipath
PASS: Successfully run wipedisk on a AIO-SX w/o multipath
