MODULES-1522 Add service_manage parameter
Merge pull request #541 from bemosior/master

Minor README internal resource linking fixes.
Update .travis.yml, Gemfile, Rakefile, and CONTRIBUTING.md
Add json gem

On Ruby 1.8.7, json is not built in. On Puppet 2.7, it is
not explicitly pulled in by the hiera gem. So we add it
here explicitly.
