[PATCH 00/10] #10619: wic refactoring (done)

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Hi,

This patchset contains refactoring of wic plugin system. It hopefully
makes the code more understandable and easier to read and maintain.
It reduced plugin system API to only one call: get_plugins, speed up
the system by using lazy evaluation of plugin info, shortened the code
and moved it to one module.

This is a last patchset of wic refactoring series. Although there are still
some places in wic code that I'd like to optimize, I decided to stop here.
The code looks more maintainable for me now and even though I want to make it
much better I have other tasks to do and important bugs to fix.

Just in case anybody is interested in continuing to refactor wic code I can point
out to the areas that still require refactoring from my point of view:
- make use of ArgumentParser: bug #9636
- refactor engine.py and help.py
- replace plugin code that configures bootloaders with using configuration
  files (--configfile .wks option)
- refactor source plugins
- get rid of custom runner module in favor of using subprocess
- move the rest of code from utils/ subdirectory to lib/wic/utils.py

The following changes since commit e4e061bbdadce3f4fe420768bb132f6aac5fca56:

  wic: move WicError to lib/wic/__init__.py (2017-02-16 13:24:03 +0200)
