Support metadata in configuration files

Support metadata in configuration files.

meta { 
   author = "Sally Hackenstein" 
   organization = "ponies worldwide"
   pgp_key_id = "203A5FE1"
   org_url = ""
   version = "1.0.2"
   vcs_url = "git@git"
   license = "APL 2.0"
   vcs_commit = "sha-of-commit"
   description = "installs docker and fpm"
   platforms: { 
      [ 
          { ubuntu: { versions:  ["trusty", "xenial"] },
          { centos: { .Like: [ "rhel", "fedora" ]  }, 
          { "Mac OS X": all }   
      ]
   }
}

Some ideas:

• Fields should be optional
• Platforms can be a little tricky, so we probably want to have some kind of matching and just warn if the platform doesn't match. The main match is the ID.
• For platform matching we can probably use the constraint engine + built in functions { "centos": [ "> 7" ] } all -> match all versions .Like -> match the LIKE field in /etc/os-release
• For platform on linux distributions we can use the "like" function to match similar.

Would it make sense for these things to be parts of module?

seems like this would be more like module metadata within a module, instead of the call to the module itself

[BrianHicks]

Seems like this should ship with a converge info x.hcl command to view this information

[stevendborrelli]

We could probably dump the platforms key for the first version.

Let's say that the initial UI for this is converge info x.hcl so we can move forward with it.
