**Describe the issue**
In the latest version (22.2.2.1) clickhouse-client ignores `port` parameter from config file.
 
**How to reproduce**
Create `config.xml` with arbitrary value for `port` parameter. 
```
<config>
    <port>9001</port>
</config>
```

Run `clickhouse-client` with custom config file
```
# clickhouse-client --log-level trace -c config.xml
Processing configuration file 'config.xml'.
ClickHouse client version 22.2.2.1.
Connecting to localhost:9000 as user default.
Connecting. Database: (not specified). User: default. Uncompressed
Code: 210. DB::NetException: Connection refused (localhost:9000). (NETWORK_ERROR)

Uninitializing subsystem: Logging Subsystem
```

The output indicates that it's used default port value (9000) instead of the value from config file (9001).
