chore(telemetry): add process tags

[dubloom]

This PR implements this RFC for telemetry.

Add process_tags to telemetry configuration

Testing

• There is already a test testing the exact config so we know that if we are not enabling the process tags, it is not in the config
• Check process tags are in the telemetry configuration when enabled.
