Sets the {@link BiFunction} to use to sanitize request content before logging. It is common to have the
{@link BiFunction} that removes sensitive content, such as an GPS location query, before logging.
If unset, will not sanitize request content.

@throws IllegalStateException If both the log sanitizers and the {@link LogFormatter} are specified.
@deprecated Use {@link LogFormatter} to set the sanitizer.
