This code sample will delay sending the request by 2 seconds:
```php
$response = $client->request('GET', 'https://symfony.com/');
$response->getInfo('pause_handler')(2);
```
Unlike "competing" HTTP clients written in PHP, this one works while streaming a request/response. This means this PR allows implementing delays before retries but it also enables throttling the streams while still maintaining async/multiplexing.
Returning the handler as an info item saves adding a new method and thus plays well with decorators, without requiring a new dedicated interface.
While this can be used directly, the target use case is within an async-decorator, by using [the `AsyncContext::pause()` method](https://github.com/symfony/symfony/pull/36779/files#diff-1d1f61631f4f5e84634e7c3dac6f208cR89).
As a bonus, this PR improves `NativeHttpClient` by making it able to count the maximum number of open connections *per-host*.
