Introduces a single-flight call to a function's health endpoint to verify that it is registered with an Istio sidecar (Envoy) before letting the invocation through. Results are cached for 5 seconds, before a probe is required again. Tested without Istio, with probe_functions environment variable set to true, I saw a probe execute in the logs. Fixes: #1721 for Istio users. Signed-off-by: Alex Ellis (OpenFaaS Ltd) <alex@openfaas.com>
