Element block-device-efi-lvm has been added which is like
block-device-efi but defines an LVM logical group in the root
partition. Three logical volumes are defined in that group, mounted to
/, /var, and /home.
This volume layout will not meet all requirements, but this is more of
an example demonstrating the capability to encourage more usage of
this existing feature.
This is based on the overcloud-partition-uefi element in
tripleo-image-elements, and I believe this capability is too useful to
have the only working example buried in a related project repo.
This change also fixes the element string matching in
_arg_defaults_hack, the 'vm' test was also matching against 'lvm' and
'block-device-efi-lvm' elements. Also the 'block-device-' test now
properly tests for this being the prefix of the block-device element.
This change also makes block-device-efi fsck-passno compliant with the
documentation[1] so that / has value 1 and all other mounts are set to
2.

When I said in I8594d1fe05242f246a5809740a115ab2f84ac5a3 that 12 MiB
ought to be enough, I should have expected that I would be proven wrong.
While 12 MiB is enough to fit shim-x64 and grub2-efi-x64, yum fails to
update these packages to newer versions:
Transaction check error:
installing package shim-x64-15-2.el7.centos.x86_64 needs 7MB on the /boot/efi filesystem
installing package grub2-efi-x64-1:2.02-0.76.el7.centos.1.x86_64 needs 3MB on the /boot/efi filesystem
Error Summary
-------------
Disk Requirements:
At least 7MB more space needed on the /boot/efi filesystem.
It is recommended that the ESP partition be much bigger. This commit
bumps its size to 550MiB, following guidelines from Rod Smith to avoid
incompatibilities with some EFIs [1].

8 MiB is not enough when using the grub2 element with centos7 images,
which installs binaries from the shim-x64 and grub2-efi-x64 packages
under /boot/efi. 12 MiB ought to be enough for anybody.

In the prior change we added block-device-[mbr|gpt|efi] elements to
create appropriate disk-layouts.
This adds an environment flag to each so the bootloader can install
the right thing. The EFI install path is updated to work with this
(this part a copy of I572937945adbb5adaa5cb09200752e323c2c9531)
We do some basic sanity checking in the block-device elements;
e.g. mbr is not suitable for aarch64, and efi is not suitable for
power.
This updates the bootloader to install EFI where appropriate

This moves the block-device default out of the "vm" element and into a
selection of other elements. There's "mbr" which retains the status
quo. There's an EFI version that has the boot/grub partitions as
required. In between there's the GPT only version, which is useful
for architectures like power without EFI, but still want possible
larger disks using GPT.
