Set NOTEST variable to skip tests in papr

The papr test with ansible is really handy for setting up test nodes.  However,
most of the time you want to run the tests manually, specifically the integration
tests.  Passing NOTEST=1 will allow you to skip gofmt, lint, and friends and will
exit before the integration tests.
