docs: Sets the {@link Function} to use to sanitize request, response and trailing headers before logging.
  It is common to have the {@link Function} that removes sensitive headers, like {@code "Cookie"} and
  {@code "Set-Cookie"}, before logging. This method is a shortcut of:
  <pre>{@code
  builder.requestHeadersSanitizer(headersSanitizer);
  builder.requestTrailersSanitizer(headersSanitizer);
  builder.responseHeadersSanitizer(headersSanitizer);
  builder.responseTrailersSanitizer(headersSanitizer);
  }</pre>
