sap-term-changes: Rename black/white according to SAP

SAP is dropping the use of master/slave and blacklist/whitelist. It wants its language to be as inclusive as possible and is replacing the well-known terms with alternatives, depending on usage. Shall we rename blacklist/whitelist terminologies as well?

This would be a breaking change and would require a doc to list down the migration step. I'm happy to edit that page but couldn't find it. It could be written on change log file as well.
