Title:
  [FFe] Add Intel RAID/RST detection with NVMe devices

Status in OEM Priority Project:
  In Progress
Status in ubiquity package in Ubuntu:
  In Progress

Bug description:
  [Impact]

  If the system has "Intel RST" mode enabled, we can't see its disks
  because there is no support in the Linux kernel for them.

  We can detect this situation and tell the user, directing them to
  documentation which tells them how to work around it.

  [Test Case]

  On a system (probably bare metal), turn on RST/Intel RAID mode and try
  to install from Ubiquity (GTK frontend only). You should see a page
  directing you to documentation (to be created).

  [Regression Potential]

  Some case will be different, especially the system doesn't have AHCI
  when RAID mode was set in BIOS, so that PCI attribute "remapped_nvme"
  is gone.
