Create application face

[yoursunny]

Provide an API for applications to create a face toward the application.

In the request, the application should provide addressing information for the forwarder to reach the application.

A local application (running on the same node as the forwarder) uses memif transport, and should provide:

• control socket file name
• interface identifier
• (optional) MTU

A non-local application (connected via Ethernet) uses Ethernet transport, and should provide:

• application side MAC address and VLAN ID
• forwarder side MAC address and VLAN ID

In the response, the agent should return a face identifier for use in prefix announcement command (#6).
