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.

Description

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.
