Reporter for current version of cf-test-helpers does not redact sensitive data

[Freakin]

Specifically for InitiateUserContext, the NewCmdRunner which performs the cf auth command reports the password in clear text.

This coupled with the inability to re-use an existing org/space and user and instead require admin credentials will expose sensitive data in logs.

Newer versions of cf-test-helpers (used by cf-smoke-tests) leverage a Redacting Reporter which removes sensitive information from output.

Our organization runs mysql lifecycle tests from concourse on a regular basis and without making local changes to vendored cf-test-helpers to use a regular user context our admin credentials would be exposed in concourse task logs.
