stable:kilo: testresources 2.0.0 require pbr > 1.8 but pbr is capped too low in kilo

[Tony Breeds]

Testresources 2.0.0 was released recently, this release included adding pbr>=1.8 to its requirements list. However, on the kilo we cap pbr at <1.0. So pulling in testresources 2.0.0 (and future versions) will break things.

[Tony Breeds (o-tony)]

We can't just cap testresources in kilo as oslo.db has an uncapped requirement on testresources. So when we install from pypi we fail anyway with:

So the way forward is
1. Land a devstack chnage that manually installs testresources<2.0.0
2. Land a review to cap testresources
3. Sync oslo.db with g-r
4. release oslo.db as 1.7.5
5. revert the patch in 1

I'll create the require reviews and set the topic to fix_testresources

    Force testresources<2.0.0 outside of g-r

    There exists a chicken'n'egg problem where we need to capp testresources
    but we can't because testresources is messing up the gate.

    Manually for that cap until we can land and release fixed packages.

So Steps 1-4 are complete

step 5 has been proposed https://review.openstack.org/#/c/308702/ but waiting on merging to verify it works as expected.

Once 308702 merges we can close this bug
