CMP-3739: Add a noop integration test target

We're setting up the ability to run integration tests that exercise how
the library works against a real OpenShift cluster in
openshift/release#69409.

This commit adds a new make target so that we can run integration tests
in isolation, making it easier to have dedicated jobs for specific test
scenarios.
