Site maintenance middleware SEO friendly

## How to usage

Create instance of middleware as you want (we use [named constructors](http://verraes.net/2014/06/named-constructors-in-php/)) and add it to middleware runner.

```php

$date = DateTime::createFromFormat('Y-m-d H:i:s', '2025-11-30 11:12:13');

$middleware = MaintenanceMiddleware::createWithRetryAsDateTime($date, $psr17ResponseFactory);

$middlewareRunner->add($middleware);

$middlewareRunner->run();

```

## Features

* Setup 503 status code,

* Supports `Retry-After` header (as seconds or HTTP-date),

* Supports `Redirect` header (redirect page after `Retry-After` time).
