Handle networkx 2.0 update

[Ian Wienand]

networkx 2.0 has been released, but is backwards incompatible with the 1.0 versions. Code needs to be ported to the new release

This is for tracking this to remove the constraints

Projects that wish to test with the new networkx can create a gerrit review depending on https://review.openstack.org/505973

Requirement.parse('networkx<2.0,>=1.10'), {'pypowervm'})
Requirement.parse('networkx<2.0,>=1.10'), {'diskimage-builder'})
Requirement.parse('networkx<2.0,>=1.10'), {'taskflow'})

we don't control the pypowervm project unfortunately, but diskimagebuilder and taskflow should still start.

It looks like taskflow is the real issue here. It is relying on the nodes_iter method that was removed in networkx 2.0. See https://networkx.github.io/documentation/stable/release/release_2.0.html?highlight=nodes_iter for how to do that with networkx 2.0.

There may be other issues that also need to be addressed. See https://networkx.github.io/documentation/stable/release/migration_guide_from_1.x_to_2.0.html

I tagged my fix in Vitrage as 'partial-bug' because it fixes the bug for now, but we don't have tempest test with networx 2.0 yet, so if anyone pushes code that isn't compatible with networx 2.0 the bug returns.

We try to avoid running all tempest tests twice as it's time consuming. If anyone has a solution for this problem (other than supporting only networx 2.0) in theirs project, I would love to hear about it.

In the future we hope to support only networkx 2.0 (with versioning) and then the bug will be closed completely.
