T
Bill(Shuzhou) Liu 14c9c17292 RDC python binding 
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.
