Title: Add support to customize Parallels Vagrantfile

- convert key from snake_case to dash-case (prevents ugly yaml using
quoted keys)
- the customize hash below should be considered as a default to allow one to
close the vm window if Parallels Desktop is open:

```yaml
- name: parallels-vm
driver:
provider: parallels
box: parallels/centos-65
customize:
on_window_close: keep-running
```

converts to:

```ruby
c.vm.provider :parallels do |p|
p.customize ["set", :id, "--on-window-close", "keep-running"]
end
```
