Add support for vagrant-parallels provider to Vagrantfile

[knazarov]

The provider allows to use vagrant with Parallels Desktop.
This is because people are asking for it:
Parallels/vagrant-parallels#84

@racktear ... as per thread on vagrant-parallels, this appears to work (in terms of launching the VM and running chef command to load various packages).. although as per the instruction in the readme to this repo, on completion, various ports should be forwarded from the VM back to the localhost, including 8888 to access iPython Notebooks in the browser. That is not happening. I'm wondering if port-forwarding in the Vagrantfile is handled properly by vagrant-parallels plugin, or if some other tweaking is needed? Any suggestions? Thanks

@Analect unfortunately, port forwarding is not yet supported in vagrant-parallels. This is due to limitation of command-line tools in Parallels Desktop. Either you need to connect to the machine directly by its IP address, or set up port forwarding from Parallels Desktop GUI

@racktear: that manual approach worked for now. Thanks.
