zhiyuan_cai bfe02339b3 Fix DevStack script error 
1. What is the problem
When running DevStack script of the Tricircle, during the setup
of Nova_apigw, script tries to add some configuration options to
the Neutron configuration file. However this file doesn't exist
at that time, thus script fails.

2. What is the solution to the problem
Stop modifying the Neutron configuration file during the setup
of Nova_apigw. Instead, we modify that file during the setup
of Neutron server.

3. What the features need to be implemented to the Tricircle
   to realize the solution
No new features. Some lines of scripts are removed.

Tricircle

The Tricircle provides an OpenStack API gateway and networking automation funtionality to allow multiple OpenStack instances, spanning in one site or multiple sites or in hybrid cloud, to be managed as a single OpenStack cloud.

The Tricircle and these managed OpenStack instances will use shared KeyStone (with centralized or distributed deployment) or federated KeyStones for identity management.

The Tricircle presents one big region to the end user in KeyStone. And each OpenStack instance called a pod is a sub-region of the Tricircle in KeyStone, and usually not visible to end user directly.

The Tricircle acts as OpenStack API gateway, can handle OpenStack API calls, schedule one proper OpenStack instance if needed during the API calls handling, forward the API calls to the appropriate OpenStack instance, and deal with tenant level L2/L3 networking across OpenStack instances automatically. So it doesn't matter on which bottom OpenStack instance the VMs for the tenant are running, they can communicate with each other via L2 or L3.

The end user can see avaialbility zone(AZ) and use AZ to provision VM, Volume, even Network through the Tricircle. One AZ can include many OpenStack instances, the Tricircle can schedule and bind OpenStack instance for the tenant inside one AZ. A tenant's resources could be bound to multiple specific bottom OpenStack instances in one or multiple AZs automatically.
