2. Add a new web ui "HBCK Report" page to display checking results.

This feature is enabled by default. And the hbck chore run per 60 minutes by default. You can config "hbase.master.hbck.checker.interval" to a value lesser than or equal to 0 for disabling the chore.

Notice: the config "hbase.master.hbck.checker.interval" was renamed to "hbase.master.hbck.chore.interval" in ~~HBASE-22737~~.

Description

See ~~HBASE-21965~~. There may have two type of failed splited/merged regions. One is orphan region on filesystem. Another one is unassigned daughter regions or merged regions. Plan to add a seperate hbck.jsp for them. Will add more hbck problems to this UI in future.
