Configure the otel-collector for `hack/compose` to use it for processing
traces and forwarding to jaeger. This simplifies the configuration and
also opens up the ability to configure additional behavior around traces
and metrics for debugging.
This also removes the automatic override file and the gitignore file. It
wasn't really working well for me and made it difficult to share
extensions to the development environment. I'm going to try something
different for that in a different change.
