Quantum requires oslo.config 1.2.0a2, but it doesn't get installed

[Mark McLoughlin]

See here:

Basically, if oslo.config 1.1.x is installed, then 1.2.0a2 doesn't get installed from the url in pip-requires because our metadata looks like:

  requires.txt:
     oslo.config

  dependency_links.txt:
     http://tarballs.openstack.org/oslo.config/oslo.config-1.2.0a2.tar.gz#egg=oslo.config

What we really need is a change in pbr to turn a URL like this:

  http://tarballs.openstack.org/oslo.config/oslo.config-1.2.0a2.tar.gz#egg=oslo.config-1.2.0a2

into

  requires.txt:
     oslo.config>=1.2.0a2

  dependency_links.txt:
     http://tarballs.openstack.org/oslo.config/oslo.config-1.2.0a2.tar.gz#egg=oslo.config-1.2.0a2

However, without that, Quantum's packaging metadata is quite seriously broken

    Revert dependency on oslo.config 1.2.0

    Fixes bug #1185174

    This reverts commit b8b2c4e, 2f13345, 362bd7f, 8da2fb7 and 956b873.

    We don't yet have the infrastructure in place to use latest oslo.config
    in the gate or even get the correct metadata for it in our packaging.

    The gory details are here:
