[telemetry] fix and refactor the PD processing

[superwhd]

This PR refactors the telemetry code processing PD info to achieve two goals:

• Handle the error when calling OT API. Previously the issue was ignored which may cause uploading wrong data.
• Introduce helper methods for processing PD info.
• Fix the D-BUS unit test and check more fields.

If this PR looks good maybe we can also refactor other sections of telemetry processing.
