Exclude freebsd and ability to disable cache dir

[afiune]

We are excluding FreeBSD systems and also adding the ability to disable
the cache_directory by setting it up to false in the kitchen.yml
file.

Example:

platforms:
- name: ubuntu-12.04
  driver:
    cache_directory: false

Closes #260
Closes #256
Closes #257

Hi guys,

This is not working for me in the following case (I'm using bento/freebsd-10.3):

platforms:
  - name: freebsd-10.3
    driver:
      # Ensure we have the latest version
      pre_create_command: test/scripts/freebsd/vagrant_init.sh
      vagrantfiles:
        - test/vagrantfiles/freebsd_init.rb
      customize:
        memory: 4096
        cpus: 4
        audio: "none"
        natdnshostresolver1: "on"
        natdnsproxy1: "on"
        pae: "on"
        largepages: "on"
        usb: "off"
        usbehci: "off"

I guess it's because it's matching for strict freebsd as platform name.

Here is the output for my case: https://gist.github.com/amontalban/d97411f769c49d5ae8918a61c1d01d88

Thanks!
