Support for flannel in server mode via networks endpoint.

[ashcrow]

This adds support for using flannel in client-server mode. For more information please see https://github.com/coreos/flannel/blob/master/Documentation/client-server.md

The following endpoints have been added:

• /api/v0/networks/
• /api/v0/network/{name}

A network is defined via a name, type, and options.

• name: The name of the network
• type: The type of network (currently flannel_etcd or flannel_server)
• options: Any options to define the network (currently address for flannel_server)

Example:

  {
      "name": "mynetwork",
      "type": "flannel_server",
      "options": {
          "address": "192.168.152.101:8080"
      }
  }

Just asking: is there some reason why network options needs to be split out as a separate JSON object? Seems like address and any other options could sit alongside name and type without conflict. If it's just convention that's fine; no strong opinion.

At this point it would be fine to have address sit along side but if/when other networks are added I believe they will end up taking vastly different options. Instead of trying to guess them I went with a fuzzy json object.

Makes sense. On further thought, probably better practice to keep the static and variant parts separate (as you have it).
