> The purpose of this change is to allow publication or storage of counters while the job is running.
> Introduced two new variables to hive-default.xml and HiveConf.java: "hive.client.stats.publishers" and "hive.client.stats.counters". First one specifies classes names, whose instances will be executed by HadoopJobExecHelper.java (similarly as hooks are) in its method progress(ExecDriverTaskHandle): MapRedStats. Second one specifies list of counters that any client stat publishers should publish or stored. Details regarding format of this list is up to a specific deployment (it is up to client stats publishers to parse it), yet it is required to use display names of counter groups and counters.
> Added interface ClientStatsPublishers in org.apache.hadoop.hive.ql.stats package, that must be implemented by all stats publishers.
> Added code to progress(ExecDriverTaskHandle): MapRedStats from HadoopJobExecHelper.java that puts counters' values to a Java map and then executes registered client stats publishers giving them that map and running job id. Added two new methods to HadoopJobExecHelper: extractAllCounterValues(Counters) and getClientStatsPublishers() that are used by code from previous sentence.
> Made cosmetic changes in two other classes
