This switches the code to use networkx for the digraph implementation.
Note that the old implementation specifically isn't removed in this
change -- for review clarity. It will be replaced by a base class
that defines things properly to the API described below.
Plugins return a node object with three functions
get_name() : return the unique name of this node
get_nodes() : return a list of nodes for insertion into the graph.
Usually this is just "self". Some special things like partitioning
add extra nodes at this point, however.
get_edges() : return a tuple of two lists; edges_from and edges_to
As you would expect the first is a list of node names that points to
us, and the second is a list of node names we point to. Usually
this is only populated as ([self.base],[]) -- i.e. our "base" node
points to us. Some plugins, such as mounting, create links both to
and from themselves, however.
Plugins have been updated, some test cases added (error cases
specifically)

This patch introduces stevedore plugin mechanism for use
with the block device layer. This makes it possible that
other projects pass in their own block device plugins.

Sphinx 1.5 fails with current pbr (needs new pbr release, see change
I52d45fa0a0d42de690d3a492068f7bb03483a224.
For now, set warnerrors to False to be able to use this.
Also, remove duplicate requirements line.
Also, update to new sphinx version to show that this works.
This is in reaction to the failure in
Ia184446fe34c49a48ca079c828157ea34e662d4b.

Move dib-run-parts from dib-utils into diskimage-builder directly.
For calling outside the chroot, we provide a standard entry-point
script. However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element. I believe this to be the KISS approach.
This removes the dependency on dib-utils. We have discussed this
previously and nobody seemed to think retiring dib-utils was going to
be an issue.
This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

Currently, running sphinx_build fails for us because we depend on
diskimage-builder in our sphinx conf.py. This causes doc generation
on sites like rtfd to fail unless they install the diskimage-builder
module beforehand. We can, alternatively, import pbr directly and not
require the module as part of doc generation.

Being able to discover DIB's version from the command itself is
convenient. This patch adds a --version option to the disk-image-create
command, failing gracefully if diskimage-builder is not installed.
This adds an explicit dependency on pbr to the requirements since this
is required to run diskimage_builder/version.py outside of a test
environment.
This patch consciously chooses to only provide the long-form option
and no '-v' to allow for the future possibility that a '-v' might
indicate '--verbose' in the future.

flake8 is called directly by dib-lint, so this is a hard requirement
to be installed for dib-lint to work outside of tox. This came up
when proposing a dib-lint job for the nodepool elements in
project-config (I28459a9bbaaa6175d03dbe753498849a75942538)

The svc-map element expects to be able to "import yaml", we should ensure
it's installed alongside DIB.

Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.
This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.
