Puppet Module Gem Dependency Metadata and Installation

Puppet module metadata.json currently are only concerned with module dependencies. Some modules have gem dependencies that needs to be installed on the master, and the metadata.json file should either include these dependencies or refer to the module Gemfile regarding this dependency.

The additional info should allow the puppet module tool list the gem dependency and optionally install them as well.
