telemetry: Enable data fields that were disabled

#8617 disabled the telemetry
fields as those database queries were causing heavy CPU performance.

#8858 fixed that issue by
adding indexes for those queries.

This PR also adds tracing for the telemetry data provider so that we
can also count how long they take usually, and how frequently these
are called.
