In anticipation of puppet 4, start trying to deal with puppet 4 things
that can be helpfully predicted by puppet lint plugins. This patch also
corrects lint errors caught by the puppet-lint-absolute_classname-check
and puppet-lint-empty_string-check gems as well as arrow alignment
which wasn't being caught under the system version of puppet-lint.
