We need to do this as we can't fix pylint without networkx as that
failes requirements-chak due to us having a cap on networkx and we can't
uncap networkx as part of tripleo-buildimage installs without
constratints which gets us 2.1 and DIB desn't support 2.x

One of the pylint dependencies has updated to be python3 only; this
version of pylint correctly caps things so it still works with
python2.
This also exposes that we need to uncap networkx due to
I34045f87ca19c2f184b040f4d89347374cce518b. We should remain on
version 1 for now thanks to upper-constraints, but we need to maintain
the lower-constraint.

Support different versions of networkx
Since the entry of networkx 2.0 nodes has a different
behaviour. Checking if dg.nodes is iterable is enough to add
compatibility for new/older versions.
