    # Creates a new CookbookUploader.
    # ===Arguments:
    # * cookbooks::: A Chef::CookbookVersion or array of them describing the
    #                cookbook(s) to be uploaded
    # * path::: A String or Array of Strings representing the base paths to the
    #           cookbook repositories.
    # * opts::: (optional) An options Hash
    # ===Options:
    # * :force  indicates that the uploader should set the force option when
    #           uploading the cookbook. This allows frozen CookbookVersion
    #           documents on the server to be overwritten (otherwise a 409 is
    #           returned by the server)
    # * :rest   A Chef::ServerAPI object that you have configured the way you like it.
    #           If you don't provide this, one will be created using the values
    #           in Chef::Config.
    # * :concurrency   An integer that decided how many threads will be used to
    #           perform concurrent uploads
