[neutron] rootwrap filters should be copied to /etc/neutron

[Rodolfo Alonso]

Neutron lib "_neutron_setup_rootwrap" method should be copying the rootwrap filers too, along with the configuration file. This issue is being notice in the grenade jobs. E.g.: installed file [1], expected file [2].

Actually this issue seems to be related to grenade. When executing ``grenade/projects/50_neutron/upgrade.sh``, this script is calling ``install_neutron`` method. But the rootwrap files are copied during the ``configure_neutron`` step (that is done after the installation step).

Same as other configuration files (dhcp_agent.ini, metadata_agent.ini, etc), the grenade upgrade step should manually handle the rootwrap files.

    Update the rootwrap config when upgrading Neutron

    As reported in the related bug, the rootwrap filters are not updated
    between versions. This patch calls the devstack method that setups
    the Neutron rootwrap configuration and filters.
