Separate OPT_OUT_PROMPT from OPT_OUT_COPY

Not all Python applications will use a CLI interface; for non-CLI
applications, the content of the new `OPT_OUT_PROMPT` constant would be
irrelevant. This separation enables `OPT_OUT_COPY` to be used more
widely, and `OPT_OUT_PROMPT` to be used when it makes sense.
