Bill(Shuzhou) Liu aeba7b0f91 Integrate RDC with Grafana
A new Grafana dashboard file rdc_grafana_dashboard_example.json
has been added to the folder python_binding. User can import
this dashboard to monitor multiple compute nodes.

To display the host name only in the dashboard, the
rdc_prometheus_example.yml is also changed to create a new label
short_instance which will not have the port number.

Bill(Shuzhou) Liu 151520b97e 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.

Bill(Shuzhou) Liu 9209c6c516 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.
