Fuel for OpenStack

Support multiple networks per cluster

Registered by Ryan Moe on 2014-02-03

Allow creation of multiple networks of all types (PXE, Public, Storage, Management) in order to support more complicated network topologies

Intended Workflow:

Cloud operator wants to deploy with leaf and spine network architecture:
  - Creates new cluster
  - Creates one node group per rack of machines
  - Creates networks for each node group and sets IP ranges each network
  - Boots machines
  - Nodes are automatically assigned to node groups based on DHCP address

Cloud operator wants to deploy using single L2 domain:
- Current workflow will continue to work with no modifications.

Feature Lead: Ryan Moe
Mandatory Design Reviewers: Andrew Woodward, Aleksey Kasatkin

QA: Yegor Kotko, Artem Panchenko
