Packstack Ocata does not configure nova for placement API

[Arslan Qadeer]

After successful installation of OpenStack Ocata from PackStack, Nova Compute service cannot show up because of undefined parameters in [placement] section in nova.conf. Following are the nova-compute logs:

Even after manually populating those parameters as mentioned below it did not work for me.

    Add support for Packstack to configure the new Nova requirements

    The Nova placement API is now required from Ocata onwards[1][2].
    This patch configures it to live generally side by side the nova API.

    Also, after a nova compute is set up, we need to call "nova-manage
    cell_v2 discover_hosts" to set up the host in a cell.
