I got quite confused what this was trying to tell me at first. It's
saying that you requested an element but another element already
provides that element, so we don't know which one to choose.
To help clarify the situation to the user, keep track of what is
providing elements so we can describe where the conflict came from.

Use standard logging module for output. Add some basic testing of
error messages to the unit-tests. Use the logging_config module to
setup the logging for interactive use.

This adds some fixtures to ensure the log output is what we expect,
along with ensuring we test the operation of the debug environment
variables.

This adds a common usable logging configuration for DIB, that
can be used by different python tools or elements.
This change is a factored out patch from the block device
refactoring.

A sanity check that cache-url does the right thing when presented
with the appropriate curl return codes. This change brings in the
test code for scripts from tripleo-image-elements, which needs to
be factored out into a place both projects can use it.
I'm stubbing out curl so we don't have a dep on curl in our unit
tests, and because I've seen some strange behavior out of curl in
the gate that caused random failures in this test.

Add a new test_no_dup_filenames module to help ensure we don't have
duplicate names across elements.

The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.
Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.
Remove all of the lines, because sanity.

To ensure that we have the list of provided elements from the
command line before looking up dependencies, use a deque and
popleft() to take the elements on a first-in/first-out basis.

Closes-Bug: #1303911
An element can define a list of elements provided by itself. This allows
using an alternative element and keeping element dependencies at the
same time. This will be needed for example for mariadb element which will be
an alternative to mysql element - mysql dependency can be kept everywhere
but user can choose mariadb explicitly as a replacement by putting "mysql"
into "element-provides" file.

This commit refactors the python code in diskimage_builder slightly. This is
in preparation for a larger review that adds more functionality to the python
code, namely the ability to apply elements to the current system as opposed to
a chroot. Further, the refactorings can stand on their own for better clarity.
They include:
- renaming elements.py to element_dependencies.py. Adds clarity about the
purpose of this module.
- updating other code for this rename.
- move tests into a tests submodule.
