Description

In various scenarios it is helpful to know a guaranteed timestamp up to which all data in a table was major compacted.
We can do that keeping a major compaction timestamp in META.
A client then can iterate all region of a table and find a definite timestamp, which is the oldest compaction timestamp of any of the regions.
