    Add api extension for new network fields.

    This uses the existing api extension to implement the actual control
    of the fields, but the check is based on a new dummy extension
    called os-extended-networks.

    Api sample tests added for new extension.

    DocImpact: Adds an extension that enables extra fields for network
    create. The new fields are:
      mtu: int (default flag) if set, nova sets the mtu on bridge. This
           allows network_device_mtu flag to be set per network.
      dhcp_server: ip (default == gateway) if different from gateway, sets
                    nova to assume gateway is external.
      enable_dhcp: bool (default true) false will disable dhcp on network.
      share_address: bool (default flag) if specifed, network will have
                     the same dhcp ip on every host. This allows
                     share_dhcp_address flag to be set per network.
      allowed_start: ip if specified, reserves all ips before allowed_start.
      allowed_end: ip if specified, reserves all ips after allowed_end.

To add this to the API docs, create a new os-extended-networks.wadl file and document the parameters as shown above in the commit message.

Since this is a Compute API v2 extension, the os-extended-networks WADL needs to go here:
https://github.com/openstack/api-site/tree/master/api-ref/src/wadls/compute-api/src/v2/ext

and then the extensions chapter should point to the WADL file:
