Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.
This patch factors out the creation and deletion of the local
loop image device handling into a python library.
The main propose of this patch is to implement the needed
infrastructure. Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

This reverts commit 5184d02a7c.
The decision was made to go with fstrim because it is faster and more
universal that zerofree. The related-id has the patchset that implements
fstrim.

If the image has an ext filesystem and the zerofree utility is present
on the build system then run zerofree. This should make images as
compressable as possible which is a nice feature when building
compressed qcow2 images.

speedup section explains the user how to sppedup image build by using
tmpfs. The correct user guide to have this section, is the user guide
about image building rather than the installation user guide.

End user docs would benefit from a section about the byte-to-inode
ratio, and why it's set the way it is. This update explains why
and how to manipulate the ratio depending on the intended use.

Install-types are a user facing feature, not just for developers. Lets
move the docs on them in to the user guide.

Our docs are very developer focused. Lets create a separate user guide
to help new users get started.
