Mark McLoughlin 3102bd700a 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:
