f314df12c3 Refactor: use lazy logging
As described in pep282 [1], the variable part of a log message
should be passed in via parameter.  In this case the parameters
are evaluated only when they need to be.

This patch fixes (unifies) this for DIB.

A check using pylint was added that this kind of passing parameters to
the logging subsystem is enforced in future.  As a blueprint a similar
(stripped-down) approach from cinder [2] was used.

deb832d685 Create and use plugin/node abstract classes
This completes the transitions started in
Ic5a61365ef0132476b11bdbf1dd96885e91c3cb6

The new file plugin.py is the place to start with this change.  The
abstract base classes PluginBase and NodeBase are heavily documented.
NodeBase essentially replaces Digraph.Node

The changes in level?/*.py make no functional changes, but are just
refactoring to implement the plugin and node classes consistently.
Additionally we have added asserts during parsing & generation to
ensure plugins are implemented PluginBase, and get_nodes() is always
returning NodeBase objects for the graph.

45272343c5 Add weights to digraph
Because in some cases (e.g. partitioning) the order is needed,
add weights to the digraph to get an (somewhat) stable
topological sort.

6f90daca7f Use check_output
The await function is essentially a non-standard check_output call.
Let's use standard calls to increase maintainability.

59a1fc6546 Add sort_mount_point method
As this method can be introduced without any dependency,
provide it on an independent change to simplify reviews.
This is a partial refactor based on

ec7f56c1b2 Refactor: block-device handling (partitioning)
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.
