Misc updates for changes in neutron packaging

1) neutron-plugin-metering-agent package renamed to neutron-metering-agent
   (existing installs will automatically upgrade to the new package)

2) The neutron-l3-agent now ships with the fwaas_driver.ini configuration
   file installed into /etc/neutron - this is picked up by the l3-agent.
