Create tests for expanded module I18N testing

Need to create tests for the following I18n and modules cases:

• Module in multiple environments
• Run puppet agent multiple times without restarting the server (not planning on doing this)
• Puppet Functions, custom facts, manifests, types, providers
• puppet agent
• puppet apply
• puppet facts
• puppet describe
• puppet resource
• Can still disable translations globally
• Verify fall back when language not available
• server side non-EN locale
