Puppet environment and module deployment

 g10k provides a general purpose toolset for deploying Puppet
 environments and modules. It implements the Puppetfile format and
 provides a native implementation of Puppet dynamic environments.
 g10k is a rewrite of puppetlabs/r10k in Go with additional
 optimizations such as:
 - caching support
 - distinct SSH keys for each source
 - parallel cloning and checkout
 - enhanced Puppetfile options
 It only supports Forge modules and Git repositories.
