Parallels provider support

I've added and tested a compatibility with [Parallels provider](https://github.com/Parallels/vagrant-parallels/).
I'm ready to support this further.

P.s. I've implemented it using the `host_address ` provider capability, which is available in 'vagrant-parallels'  v1.0.3 and later. That's why I've added a version checking. Please, let me know if you have any suggestion about that.
