1. What is the problem
The segment ID of local type network is allocated in the local Neutron
server, so it's possible that segment IDs of bridge network and local
network conflict, which results to failure when creating bridge network.
2. What is the solution for the problem
Since network AZ is implemented, we can deprecate the "local" network
type and only create a local network by specifying AZ as region name.
Before such deprecation, we change local type as the last network type
candidate to avoid users create a local type network by mistake.
3. What features need to be implemented to the Tricircle to
realize the solution
N/A
