Expose what component devices are part of a MD raid device, as well as the most common flags per-component. This will enable a future node_exporter metric showing which component of a RAID had failed. Signed-off-by: Robin H. Johnson <[email protected]> Signed-off-by: Robin H. Johnson <[email protected]>

Expose what component devices are part of a MD raid device, as well as the most common flags per-component. This will enable a future node_exporter metric showing which component of a RAID had failed.
This PR builds up top of PR 505, implementing the requested changes to detect the known RAID types on a given system.
