write metadata when test image provisioning fails

Put it in the provision-log directory as JSON. Currently, the only
captured value is the exit code. This allows some
machine-readable distinction by an external observer about why exactly
the test image provisioning failed.

Windows platform support

In order to support Windows VMs the virter calls have
to be passed the --user Administrator option.

The vms.toml files now have a new field:
    user_name = "Administrator"
should be specified for VMs that are Windows machines.
If this field is omitted the default "root" is
used (so no changes necessary for Linux-only
environments).

As a convenience the --vnc and --vnc-bind-address
options are given for all machines which allows to
debug VMs that fail to start (for example).

The example vms.toml file has been updated to
document these changes.
