# 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::REST 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
