[BUG] `harvester.install.wipe_disks=true` will attempt to wipe USB disk for ISO installation

[Mike Russell]

Describe the bug
harvester.install.wipe_disks=true will attempt to wipe a USB disk for ISO installation and error out.
Or via config:

install:
  wipe_disks: true

To Reproduce
Steps to reproduce the behavior:

1. USB ISO Installation
2. Pass in either a config.yaml link to a fileserver or just the GRUB param e on GRUB boot screen
3. Install is trying to wipe /dev/sdc which is the USB Drive that's intended to preform the installation

Workaround

• Do not use a USB Interactive ISO installation and pass in that GRUB param

Expected behavior
Parse sudo dmesg results and perform an analysis to avoid trying to "wipe_disks" on USB drives:

^ From that we can determine that a USB Mass Storage Device was detected and attached to /dev/sdb for instance.
