Allow control of the volume size to be increased from the box default
virtual_size value so that it is possible to use a box configured with a
minimal initial disk size and create virtual guests with larger disk
sizes.
Warn the user and ignore sizes that are less than the box size, and
inform them that a manual filesystem resize will be needed to take
advantage of the additional available disk space.

`virt-sysprep` will, by default, remove all `.ssh` directories from all
users' home directories. Since we need to have the default Vagrant
insecure keypair in the `authorized_keys`, this causes problems later
when trying to use the packaged box, as Vagrant is unable to log in.
`virt-sysprep` has the ability to disable options via the `--operations`
argument; the `ssh-userdir` option should be disabled.
Compare storage pool on the found volumes to avoid selecting a disk from
a different and unreachable to the domain storage pool.
Users may move between storage pools by configuring the driver which
will mean that it is possible to find the same image name in multiple
storage pools and incorrectly perform operations based on the one not
associated with the currently specified pool.
When using persistent images to attach to storage this will cause domain
creation to fail since although the image was found in one of the
storage pools, it may not be connected since it does not exist in the
storage pool requested for the VM.
Exit the synchronize block before performing calling the next item in
the middleware chain otherwise the mutex lock applies to the entire
provision sequence from that point onwards until the entire chain has
returned to the same point.
Executing a return statement inside a block does not exit the block
automatically. Instead only when the statement returned has been
processed is the wrapping block exited.
Since the return call is actually calling the next action in the chain,
this change ensures that the mutex is not held for subsequent actions
and thus allows vagrant to perform remaining actions in parallel.
Without this all provisioning of machines will always occur serially
instead of parallel when requested.
The logic is that we first gather all usable guest addresses, then
use routing information (through a udp socket) to figure out host
IP for use to connect to guest.
