Set OS network configuration

• This configuration uses named interfaces for ease.
• The network topology represents the viable minimum logical networks required to build a multinode(2) cluster (no baremetal provisioning).
• The API and PROVIDER networks are on their own physical interfaces, the TUNNEL and STORAGE networks are VLANs on another physical interface.
