Blueprint changed by Scott Moser:

Whiteboard set to:
User Stories:
Rocky runs a MAAS cluster.  The nodes have frequent turnover and installation time is time lost.  Faster installation means higher usage time.

Assumptions:
The fast path installer is intended to only support simplistic cloud-image-like installation.  Users wishing for for more complex partition layout may need to use the debian installer path.

Risks:
bootloader installation is non-trivial.  The debian installer does a good job of doing this.  If we can't re-use that logic we risk failing to boot.  UEFI boot is also complex and may be required for some systems.

Test Plans:
This code path will be used in the Ubuntu openstack CI framework to help it install faster.  That will prove at least one functional path.

Release Note:
Nodes installed through MAAS can use the fast path installer to significantly reduce installation time.  It results in a cloud-image like environment with customization available via cloud-init on first boot.
