Disable home folder sharing by default (Parallels Desktop 11+)

[legal90]

Implements GH-171 for Parallels Desktop 11+

Due to request GH-171 there was a new CLI option added in PD 11:

prlctl set <vm_uuid> --shf-host-defined <off|alldisks|home>

By default all Parallels Desktop VMs has this option set to "home", so that user's home folder (from the Mac host) is accessible for read & write from the guest VMs. In Linux VMs its content could be found at /media/psf/Home

I suggest to set this option to off for all VMs managed by our Vagrant provider, as we do for other host<=>guest integration features (see GH-215). This is needed for security reasons and helps to isolate dev environment from the Mac host.

Those users who want to override this behavior, could do it via Vagrantfile:

config.vm.provider "parallels" do |v|
  v.customize ["set", :id, "--shf-host-defined", "home"]
end

Probably, it also makes sense to do the same in Packer builder.

@legal90 Agree, it's probably a better default in Packer too.
