openstack cookbooks currently use Berkshelf 2.x and we are moving to 3.x. Berkshelf deprecated the "berks install --path" cli in favor of "berks vendor <path>". While we transition all the cookbooks, need to support both versions of Berkshelf. Change-Id: I82a203fdb9b0c2ec47daefecb361d22aca306afb Addresses: blueprint update-berkshelf
