Support watch() and unwatch() in RDC module framework

The framework now supports watch() and unwatch(), which can be used
by the telemetry library to init events or pre-fetch fields when recording
starts.
* A new header file RdcTelemetryLibInterface.h is defined for library to
  include it.
* The RdcWatchTable will not talk to RdcMetricFetcher directly anymore.
  It will call the framework watch/unwatch to dispatch it to the libraries.
* Make the python binding consistent with the current code.
