Support cache manager and watch table in rdc_lib RdcCacheManagerImpl.cc is added to implement cache of metrics. Currently, only integer mertics are supported. The cache manager provids function to retrieve the latest and history metrics from cache. It also provides interfaces to update and evict the cache. RdcWatchTableImpl.cc is added to implement watch and unwatch fields. It uses the field settings to control how frequently a field needs to be updated. We have a preliminarily performance optimization for this class as it may be called very frequently. RdcMetricsUpdaterImpl.cc is added to run the update at background thread when RDC_OPERATION_MODE_AUTO is set. After this code change, the rdcd/rdci should be able to implement basic discovery, group and dmon function. The job management function is not implemented in the skeleton rdc_lib yet.
