WL#9874: Deprecate and remove the replace utility

The replace utility program changes strings in place in files or on the standard 
input.
https://dev.mysql.com/doc/refman/5.7/en/replace-utility.html

This utility is not used by us internally and it is not a natural part of MySQL.

This WL is about deprecating this utility (5.7 server) and remove it (8.0 server).
