CreateCertAndAddCA creates a signed cert with a root CA and adds the CA to the specified cert pool.

NewTestLogger returns a new slog logger using a zap handler.

Our tests assume that there exists a DNS entry *.localhost.routing.cf-app.com that maps to 127.0.0.1 If that DNS entry does not work, then many, many tests will fail.

TestLogger implements an slog logger that can be used with Ginkgo tests.
