Rubygems access

[ashiqueps]

Hi @damacus ,

The shared account doesn't have access to all of the gems available in the test-kitchen org. Could you please add the rest of the gems?

Ruby gems has a rate limit on granting access so it has to be done across multiple times :(

This has now been completed. @ashiqueps if there are any missing repos, give me a shout please!
