HPE "Virtual Install Devices" appear as read-only block
devices, and may... or may not be visible depending on the
bios configuration state.

These devices can no longer be disabled from the bios settings
so the simplest course of action seems to be that we should
handle the existence of a read-only device.

In the event of secure erase, this is treated as a hard failure
case and a driver_internal_info flag has been added to enable
a future bypass method for knowledgable operators.

Backport note: the unit tests have been modified to account for Python 2

The lshw output is huge even on virtual machines, and it pollutes
the debug logging. This change silences it. Instead, the lshw output
is collected as part of the ramdisk logs.

IPMI SPEC[1] assignment channel number 1-11 for vendors
implementation(We an search "Channel Numbers" in section 6.3).
We met an baremetal product, like H3C, use number 8 as LAN channel.

Current code limit channel number to 1~7,
I think this can increase to 1~11.

Modify the metadata erasing call chain to retrieve a list of devices
that includes partitions in addition to disks so it can erase metadata
from all of them, otherwise incidentally recreating disk partitions
causes the Linux kernel to discover and automatically recreate some
types of storage entities (eg LVM PVs, VGs, & LVs, RAID members &
devices).
