refactor: improve telemetry api receiver listener initialization logic

[herin049]

Improves the Telemetry API receiver listener initialization logic to more closely match the logic used elsewhere in the layer. Updated the default behavior to listen on :0 by default to eliminate the need of manually specifying ports and eliminate the possibility of encountering Error: address already in use errors that are very rare and difficult to debug. The listener now handles shutdown properly by closing the HTTP listener, and several incorrect log statements have been updated with a few additional ones added.
