Subject: [PATCH 1/2] add support for boot 'network' from a vagrant
 public_network

when use a public_network in vagrant, this is how libvirt domain xml looks like (notice that the interface type is 'direct'):

    <interface type="direct">
      <mac address="08:00:27:00:00:01"/>
      <source dev="br-rpi" mode="bridge"/>
      <model type="virtio"/>
      <boot order="2"/> <!-- this boot xml node will be inserted with this commit -->
      <address type="pci" domain="0x0000" bus="0x00" slot="0x05" function="0x0"/>
    </interface>

+An example VM that is PXE booted from the `br1` device (which must already be configured in the host machine), and if that fails, is booted from the disk:
+
+```ruby
+Vagrant.configure("2") do |config|
+  config.vm.define :pxeclient do |pxeclient|
+    pxeclient.vm.network :public_network,
