Simplifies the signalling of healthcheck status from the "servers" to the "service": instead of using 2 channels to feed healthcheck status back to the Service.HealthCheck, we just give the server components direct access to the Healthcheck which they can update directly. This is possible because the Healthcheck package is threadsafe (uses `atomic.Value` for state). This pattern is consisten with how the service's Healtcheck is passed directly to cmd/collector/app package. closes jaegertracing#5307 Signed-off-by: Will Sewell <[email protected]>

There was a problem hiding this comment.
I felt like this was nicer ordering because this felt related to the logger to me since they both come from the service and are both related to "reporting status".
