Description

The current available Put API always makes a copy of the rowkey.
Let's provide an API that accepts an immutable byte array as rowkey without making a copy.
There are cases where the caller of Put has created the immutable byte array (e.g from a serializer) and will not change it for the Put duration. We can avoid making a copy again.
