`use_tls` and `pulsar+ssl://` client behavior can differ

While running Pulsar cluster proxies behind an AWS Load Balancer I ran into issues with TLS connections to the proxies using example code from this repository. Running the `examples/consumer.py` code with the client url set to an LB hostname and `use_tls=True` results in connection failures, whereas simply specifying `pulsar+ssl://` the consumer works as expected. After checking [docs ](https://pulsar.apache.org/api/python/3.8.x/pulsar.Client.html)it seems the `use_tls` argument is deprecated, but I would still expect the behavior between `use_tls` and `pulsar+ssl://` to be the same. I can provide details on the load balancer configuration if needed.

Examples with some logs (fake hostname):
```python
client = pulsar.Client("pulsar://pulsar-primary.acme.org:6651", use_tls=True)
```
This client produces connection errors like below:
```

```

After switching the client to use `pulsar+ssl://`, the example consumer code works with no other changes.
```python
client = pulsar.Client("pulsar+ssl://pulsar-primary.acme.org:6651")
```

Is this difference in behavior known and/or expected?

從 examples/consumer.py 以及 issue 中顯示的 pulsar.Client 連線選項開始。比較 use_tls=True 路徑與 pulsar+ssl:// URL 路徑，然後根據文件中已棄用的引數和回報的 Proxy 設定驗證行為；當兩種形式都處理相同的 TLS 連線情境，或已清楚記錄所支援的差異時，即表示完成。
