Move telemetry back into one file and comment it out

[jaegeral]

Comment out telemetry by default in one docker file.

We have the same for notebooks: https://github.com/google/timesketch/blob/master/docker/dev/docker-compose.yml#L102

We just commented those our for now. Default is: No traces for the beginning and who wants it just removes the comments.
