d2to1 triggers setuptools upgrade bug on old pip versions

[Monty Taylor]

pbr used to be based on d2to1, and we included it in our setup_requires. Then setuptools and distribute re-merged, and a set of depends in d2to1 cause the transient setuptools upgrade issue to surface if the user is running old distribute AND an old version of pip, potentially breaking the system.

To fix it, we removed use of d2to1 from pbr, but we're still referencing it in a few places around OpenStack. We need to remove them.

    Sync with global requirements

    And more importantly, get rid of d2to1 references.

    Skipped test-requirements because of webtest and I need the d2to1 change
