MINOR: cli: add cli_msg(), cli_err(), cli_dynmsg(), cli_dynerr()

These functions perform all the boring filling of the appctx's
cli struct needed by CLI parsers to return a message or an error,
and they return 1 so that they can be used as a single-line return
statement. They may be used for const messages or dynamic messages.
