code: protected SslHandler newSslHandler(ChannelHandlerContext context, SslContext sslContext) {
          return sslContext.newHandler(context.alloc());
      }
docs: Override to configure the SslHandler eg. {@link SSLParameters#setEndpointIdentificationAlgorithm(String)}.
  The hostname and port is not known by this method so servers may want to override this method and use the
  {@link SslContext#newHandler(ByteBufAllocator, String, int)} variant.
  
  @param context the {@link ChannelHandlerContext} to use.
  @param sslContext the {@link SSLContext} to use.
  @return the {@link SslHandler} which will replace the {@link OptionalSslHandler} in the pipeline if the
  traffic is SSL.
