With new block device definition, where content of the image
can be mounted on different partitions, is not enough with
executing setfiles on root directory. Instead of that, expose
all the mountpoints on the image, and apply setfiles on them.

This patch finalizes the block device refactoring. It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.
Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.
Notes:
* unmount_dir : modified to only unmount the subdirs mounted by
mount_proc_sys_dev(). dib-block-device unmounts
$TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9)

Closes-Bug: #1664924
The args agument was only used to find the symbol for the getval
command. Have the command pass the symbol to find in directly. We
can therefore remove the args paramater to the BlockDevice() creation.

Move argument parsing to subparsers, rather than positional arguments.
This better reflects the tool's role as a driver and allows
sub-commands to deal with arguments in a natural way.

This moves the YAML parameter parsing into the command-line driver.
It makes the argument optional so it can be taken from the environment
variable directly. The parsed YAML is passed to the BlockDevice
object.

To avoid any confusion, commands passed to exec_sudo() should be a
list of "str"s. Log a message if we see unicode issues.
This also adds a debug trace of all output. stderr is captured.
This is modified to raise CalledProcessError on failure, like
check_call(). Calls that are ok to fail will need to explicitly catch
and ignore this.
The two calls that we expect to fail are wrapped
We wish to try rolling back if one of these command raises an
exception. Modify the create handler to initiate rollback on all
exceptions.

As part of the final steps, refactor the bits belonging
to block device and functions. This is a partial refactor
from I3600c6a3d663c697b59d91bd3fbb5e408af345e4

Add a new getval call that allows to retrieve values
from the block device. Also isolating the block device
information into a 'blockdev' dictionary entry, to better
return it with the getval command.
This is a refactor from the original code at
I3600c6a3d663c697b59d91bd3fbb5e408af345e4.

The original approach was to pass each and every command
line parameter to the block device. While the block device
functionality gets extended, this is not any longer practical.
Instead of passing in all the parameters separately this patch
collects these in a YAML file that is passed in to the block device
layer.

This patch introduces stevedore plugin mechanism for use
with the block device layer. This makes it possible that
other projects pass in their own block device plugins.

Now that the main partitioning refactor patch is merged, there is
a small relict of handling partitions still in the disk-image-create
main.
This patch moves the functionality from disk-image-create to the
block-device/partitioning module: it is mostly a rewrite of the
original bash code in python.

In error scenarios there might be no loadable state available.
This patch adds some robustness handling this scenarios
by checking the result and possible bailing out.

With the old configuration structure it was only possible
to use one image and one partition layout. The new
block-device configuration uses a list at top level;
therefore it is possible to use multiple instances
of each element type.

During the creation of a disk image (e.g. for a VM), there is the need
to create, setup, configure and afterwards detach some kind of storage
where the newly installed OS can be copied to or directly installed
in.
This patch implements partitioning handling.

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.
