Wido den Hollander 0beb41b6e7 CLOUDSTACK-9395: Add Virtio RNG device to Instances when configured
By adding a Random Number Generator device to Instances we can prevent
entropy starvation inside guest.

The default source is /dev/random on the host, but this can be configured
to another source when present, for example a hardware RNG.

When enabled it will add the following to the Instance's XML definition:

  <rng model='virtio'>
    <rate period='1000' bytes='2048' />
    <backend model='random'>/dev/random</backend>
  </rng>

If the Instance has the proper support, which most modern distributions have,
it will have a /dev/hwrng device which it can use for gathering entropy.
