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.

A new folder python_binding is created for RDC python binding:
* The rdc_bootstrap.py is a python ctypes wrapper for the librdc_boostrap.so
* The RdcUtil.py defines common utilities for RDC to manage group/fieldgroup
* The RdcReader.py is a class to simplify the usage of the RDC:
- The user only needs to specify which fields he wants to monitoring.
RdcReader will create groups and fieldgroups, watch the fields, and fetch the fields.
- The RdcReader can support embedded and standalone mode.
- The standalone can be with authentication and without authentication.
- In standalone mode, the RdcReader can automatically reconnect to the rdcd when the connection is lost.
- When rdcd is restarted, the previously created group and fieldgroup may lose.
The RdcReader can re-create them and watch the fields after reconnect.
- If the client is restarted, RdcReader can detect the groups and fieldgroups
created before and avoid re-create them.
- The user can pass the unit converter if he does not want to use RDC default unit.
