Add tests for Tasks

This commit adds tests for some of the Tasks in this repo. The tests are
implemented as Go tests. The test files reside alongside the Task
definitions for convenience. See README.md for how to run them.

The tests execute against a Kubernetes cluster, including a kind[1]
cluster.
