Aaron Rosen b004985c24 NSX-v3: Initial framework for api-replay-mode
This patch includes the initial framework to allow existing
neutron deployments running different backends to be migrated
over to the nsx-v3 plugin. The main logic that is required to
do this is to allow the ability of an id to be specified for
a given resource. This patch makes this possible with the addition
of a new extension api-replay.

The reason why a new extension is needed is because the RESOURCE_MAP
is loaded after the plugin is loaded. Therefore, there is no way
for me to change the mapping directly in the plugin without creating
an extension to do so.

This patch also adds support for migrating the router-uplink and
floatingips which was missing in the previous patchset.

Here's an example output of the migration tool
running: http://codepad.org/I7x6Rq3u
