Revert "Bumping the version and adding each environment variable to a node attribute."

This reverts commit 23b2a77ba3972f584c40588d5440156f5a9444ea.

I meant to add this to a branch, not master.
Updating the Gemfile for testing to stick to moneta 0.6.0 because the newer version is causing Travis failures.
Adding a name to metadata.rb
Merge branch 'master' into apache

Conflicts:
