Perform to following tasks: 

• Modify _topic_map.yaml to move Distributed Tracing under Observability
• Search the whole docs set and replace all old occurrences of the file(s) with the new location, paying special attention to anchor tags.
• Update incoming/outgoing xrefs to reflect the change to the relative path (../)
• Run asciibinder build to confirm that the changes are correct locally. Fix any errors.
• Confirm that the topic is not used by the console by reviewing this file. If it is used by the console team, reach out to the OCP DPM.
• If redirects need to be set up, follow these steps in advance of merging your PR.
• Apply these changes to OCP 4.12+

In the topic map, initial doc headings for each component occur at the same level as the Observability overview. The Distributed Tracing entry goes before the Power Monitoring docs. 

The docs in the Observability directory will ultimately be ordered in the following way: 

Monitoring

Logging 

Distributed Tracing

Red Hat build of OpenTelemetry

Network Observability 

Power Monitoring
