[CLI] Added --chef_repo_path option

This will override the chef_repo_paths option in the config. When
specified, the directory is assumed to contain the entire chef repo
you want.

This option is put in place so that testing migrations using
`knife download` and `knife upload` is easier. If "override everything" is
a feature request you require, then please file a bug report
[COOKBOOKS] Added versioned_cookbooks support.

 - Adding "versioned_cookbooks true" to knife.rb turns on versioned cookbook mode
 - Cookbooks are assumed to be named such as:

cookbooks/
  apt-1.8.4
  apt-1.7.0
  postgresql-2.2.2

 - This allows for multiple versions.
 - Caveat: this commit requires the CHEF-3307 patch against chef 10-stable
[COOKBOOKS] Fixed regressions when versioned_cookbooks is false
[SPEC] Refactored some of cookbook_dir_spec
[SPEC] Separated cookbooks_dir and cookbook_dir spec. Added versioned_cookbooks test
