#### Description Depends on https://github.com/open-telemetry/opentelemetry-collector/pull/11209 This PR is a non-breaking implementation of https://github.com/open-telemetry/opentelemetry-collector/pull/10947. It adds a new module, `pipeline`, which houses a `pipeline.ID` and `pipeline.Signal`. `pipeline.ID` is used to identify a pipeline within the service. `pipeline.Signal` is uses to identify the signal associated to a pipeline. I do this work begrudgingly. As the PR shows, this is a huge refactor when done in a non-breaking way, will require 3 full releases, and doesn't benefit our [End Users or, in my opinion, our Component Developers or Collector Library Users](https://github.com/open-telemetry/opentelemetry-collector/blob/main/CONTRIBUTING.md#target-audiences). I view this refactor as a Nice-To-Have, not a requirement for Component 1.0. <!-- Issue number if applicable --> #### Link to tracking issue Works towards https://github.com/open-telemetry/opentelemetry-collector/issues/9429
