implement a single global dependency list

[Monty Taylor]

There should be a single global depend list and all of the projects should consume it.

Current working theory is that openstack-common can contain pip-requires and test-requires files that contain the total list, and then update.py can copy over the require entries to the target project for anything listed in the file that already exists. (so that we don't add django to nova, for instance)

Fix proposed to branch: master
Review: https://review.openstack.org/8284

[Brian Waldon (bcwaldon)]

I don't buy that this should happen in openstack-common, mainly because this isn't the goal of that project. Monty has some ideas he'll document here.

[Monty Taylor (mordred)]

After chatting some with Brian, I split out the global depends stuff into its own repo:

https://github.com/emonty/openstack-depends

If we're happy with this approach, I'll add it to gerrit. However, brian hates the name openstack-depends, so perhaps "openstack-requirements" or just "openstack-requires"?

This has been released as openstack/requirements.
