Create the rdc.h header file and librdc_bootstrap.so

Browse Source 
The rdc.h is the only header file will be provided to the user.
The inital version only includes the data structure and function
required for the job stats example.

The example folder has one example demonstrated how to use the API
to collect the job summary stats.

The RdcBootStrap.cc will dynamically load different libraries when user
select either the standalone or embbed mode. We also created a
dummy RdcEmbeddedHandler.cc for librdc.so.

In order to run the example after build, it needs to specify the
LD_LIBRARY_PATH. Assume current folder is the build folder:
LD_LIBRARY_PATH=$PWD/rdc_libs $PWD/example/jobstats

The folder is structured in following ways:
example
include
    - rdc - rdc.h (the only header file exposed to the user)
    - rdc_libs
          - impl
rdc_libs
    - boostrap
         - src
    - rdc
         - src
    - rdc_client
         - src
    - rdc_server
         - src
