nova-base for centos binary is missing oslo-policy

[Martin André]

This is obviously an RDO packaging issue, but we need to implement a workaround until it is fixed upstream. It is causing our centos-binary-deploy gate to fail:

    Add workaround to fix centos-binary-deploy gate

    The RDO nova package is missing a dependency on oslo-policy and this is
    breaking our centos-binary-deploy gate. Install the missing package in
    nova-base until the issue is fixed upstream.
