Testing

CI will be running the tests. I run a test locally by setting the environment variable manually:

=== RUN   TestOperator
  "level"=0 "msg"="waiting for" "1m51s"="before executing test suite"
Running Suite: Operator test suite - /Users/jscheuermann/go/src/github.com/FoundationDB/fdb-kubernetes-operator/e2e/test_operator
