added config option 'chef_path' for chef_solo provisioner to be independent of target systems $PATH settings. If 2 different chef versions are installed you can now point testkitchen to the binary directory one you actually want to use. E.g. chef_path: '/opt/chef/bin' to use the omnibus chef-solo instead of the one in /usr/local/bin
