Jacob Anders c5f7f18bcb Improve efficiency of storage cleaning in mixed media envs
https://storyboard.openstack.org/#!/story/2008290 added support
for NVMe-native storage cleaning, greatly improving storage clean
times on NVMe-based nodes as well as reducing device wear.

This is a follow up change which aims to make further improvements
to cleaning efficiency in mixed NVMe-HDD environments. This is
achieved by combining NVMe-native cleaning methods on NVMe devices
with traditional metadata clean on non-NVMe devices.

Adds support for express cleaning mode where hardware-assisted, fast and
secure data erasure is performed on NVMe devices that support it,
while other devices fall back to erase_devices_metadata.
The goal of this feature is to enable express node cleaning in
environments with hybrid storage configuration (e.g. NVMe + HDD).
