Maximiliano Sandoval 4d1c4ec829 http: teach the Client how to decode deflate content
The Backup Server can compress the content using deflate so we teach the
client how to decode it.

If a request is sent with the `Accept-Encoding` [2] header set to
`deflate`, and the response's `Content-Encoding` [1] header is equal to
`deflate` we wrap the Body stream with a stream that can decode `zlib`
on the run.

Note that from the `Accept-Encoding` docs [2], the `deflate` encoding is
actually `zlib`.

This can be also tested against
http://eu.httpbin.org/#/Response_formats/get_deflate by adding the
following test:

```rust
    #[tokio::test]
    async fn test_client() {
        let client = Client::new();
        let headers = HashMap::from([(
            hyper::header::ACCEPT_ENCODING.to_string(),
            "deflate".to_string(),
        )]);
        let response = client
            .get_string("https://eu.httpbin.org/deflate", Some(&headers))
            .await;
        assert!(response.is_ok());
    }
```

at `proxmox-http/src/client/simple.rs` and running

```
cargo test --features=client,client-trait
```
