Instead of multiple places handling the same thing duplicating the
logic, it's better to do it once upfront. This allows easy caching of
the results.
Additional advantage of this approach is that the config dump will
include resolved URLs. The original reference will still be available in
the copy of the original config.

If a phase is started successfully, it needs to be stopped as well. In
most cases when `stop` is called immediately after `start`, this is not
a problem.
Only when something else happens while a phase is runnning and this
something fails, Pungi will deadlock and never exit. This something
could be another phase or just main thread raising an exception.

The live_images, live_media and image_build phases have same options
that need to be specified on each image. This leads to a lot of
duplication in the config file. This patch adds global settings and
phase-level settings that allow to significantly reduce duplication.
