Configurable External Gateway Modes

Registered by Salvatore Orlando

This blueprint is a follow up of the discussion around bug 1121129.

In a nutshell, the goal is to allow users of the quantum API for specifying how a quantum router should behave when an external network is connected. For more details, please refer to the specification page.

In order to guarantee full backward compatibility the current behaviour (default SNAT and DNAT - floating IPs) enabled will be the default selection.

Plugins supporting the L3 API should not be required to support this feature too.
To this aim, this change should be implemented as an API extension.

Question:nati
There is usecase we need SNAT or DNAT on the others port.
How about keep external_network_info with current form and add,

dnat_ports= [
   port_id1,port_id2...
]
snat_ports= [
   port_id1,port_id2...
]
?
