(PDK-508) Prove that autorelations are working with puppet

This test shows that the autorelations implementation of the Resource
API does build relations. Since rspec-puppet doesn't provide matching
on compile errors, this builds a test case that compiles when make_cycle
is false, thereby proving that there is no error in the manifest, but
fails with a dependency cycle error when make_cycle is set to true.
