Add neutron-api-reply cli tool

This tool reads from one neutron server and then replays all the
of the api calls required to create the resources on another server.
It requires the dest-neutron service to be in api-replay-mode to allow
us to specify the ids of resources.

This patch migrates all resources expect for floatingips and uplinking
the router.

This patch also makes some modifications to the plugin code to make migating
security groups especially the default security group and rules that
users have added possible.
