schema-recipe: add support for veth interfaces

This patch adds recipe XML support for veth interfaces. Since veth
    devices are created in pairs, XML specification reflects this by
    encapsulating two <veth> tags in a single <veth_pair> tag. Both of these
    tags are mandatory. At the moment there are no <options> supported - you
    can specify them, but they will be ignored.

Example interface specification would look something like this:

<interfaces>
        <eth id="out_if" label="tnet"/>
        <veth_pair>
            <veth id="testifc1" netns="xyz">
                <addresses>
                    <address value="192.168.200.2/24"/>
                </addresses>
            </veth>
            <veth id="testifc2"/>
        </veth_pair>
        <bridge id="br">
            <slaves>
                <slave id="out_if"/>
                <slave id="testifc2"/>
            </slaves>
        </bridge>
    </interfaces>
