Merge "Adding template test for logging.conf"
Tests were not passing due to postgresql cookbook

Changes to the upstream postgresql cookbook broke tests.
Gemfile.lock was updated to bring in fauxhai 1.1.1 which
has these attributes mocked.

Also, Berksfile.lock shouldn't be checked in.  Removed from
this patch, since it impacts testing.

All tests should be using spec_helper

Not every test is utilizing spec_helper.  Clean up tests
so they are consistent with our other openstack tests.
Also, #require_relative allows you to load a file that
is relative to the file containing the #require_relative
statement.  We should update the remaining cookbook
tests to use this.
