Release Note

<!-- markdown -->

The `CellUtil.setTimestamp` method changes to be an API with audience `LimitedPrivate(COPROC)` in HBase 3.0. With that designation the API should remain stable within a given minor release line, but may change between minor releases.

Previously, this method was deprecated in HBase 2.0 for removal in HBase 3.0. Deprecation messages in HBase 2.y releases have been updated to indicate the expected API audience change.

Description

CellUtil.setTimestamp has been deprecated in 2.0 and is marked for removal in 3.0. Phoenix currently uses this api to set the timestamp of cells in its indexing coprocessor for tables that have mutable indexes. We can't use the CellBuilder api since this involves creating a copy of the cell which will be expensive.
