Remove old references in prep for Icehouse

A standard pre-release patch, looking for any obsolete text to remove,
and references to newly unsupported releases to remove.

Feel free to update the patch if you find other things.

Review request: this patch touches many files in a small way.
Please try and focus on the small changes, and not the rest of the
file ... since many of them do need an edit  ;)

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.
