As discussed a bit over chat, it feels a bit misplaced to me to be doing this swap file stuff for all of our tests (~40 different test functions, counting all third party apps as just one test function) when only one of them actually needs to have a swap file. This PR is partly about streamlining the VM setup process in gce_testing.go, for simplicity and speed, but also about getting our tests to use VMs that look as much like "out of the box" VMs as possible.
