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.

To comply with the new hacking>=0.8.0,<0.9 requirements,
assertEqual is used instead of assertEquals which has been deprecated,
giving the error H234.

Using ELEMENTS_DIR env variable, you can specify multiple dirs containint your elements.
It must be a ":" separated elements list.
When an element is seen in one of those lists, it will be chosen and will continue with the next element.

bin/element-info accesses it's library via a symlink:
bin/diskimage_builder -> diskimage_builder
This causes the relative path in elements.py to be
incorrect.
element-info silently fails in this situation, because
it allows missing 'element-deps' files, so that these files
may be optional.
This change causes element-info to fail explicitly if $ELEMENTS_DIR
is not set, as it now is when called by diskimage-create, and
adds tests reflecting this behavior.

Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.

This adds a new optional file to the root of elements. The
file lists dependencies which will be added to the list
requested by the user during disk image creation.
