Duo Zhang updated HBASE-21762:
------------------------------
    Release Note: 
Move the two getHbck method from ClusterConnection to Connection, and mark the 
methods as IA.LimitedPrivate(HBCK), as ClusterConnection is IA.Private and 
should not be depended by HBCK2.

Add a clearRegionLocationCache method in Connection to clear the region 
location cache for all the tables. As in RegionLocator, most of the methods 
have a 'reload' parameter, which implicitly tells user that we have a region 
location cache, so adding a method to clear the cache is fine.
     Component/s: Client

> For example, clearRegionCache, getHbck, etc. The getHbck method will be 
> marked as IA.LimitedPrivate to indicate that normal user should not use it. 
> And I think this is OK, as it is not easy to use the Hbck interface directly, 
> and the name 'hbck' also implies that it should not be used for normal case.
