docs: Sets the {@link Function} to use to sanitize request and response content before logging. It is common
  to have the {@link Function} that removes sensitive content, such as an GPS location query and
  an address, before logging. If unset, will use {@link Function#identity()}. This method is a shortcut of:
  <pre>{@code
  builder.requestContentSanitizer(contentSanitizer);
  builder.responseContentSanitizer(contentSanitizer);
  }</pre>
