Fix this error when requesting a service running
on the local backend and served by the in-server
proxy:
```python
File "/dstack/src/dstack/_internal/proxy/lib/services/service_connection.py", line 82, in open
await self._tunnel.aopen()
File "/dstack/src/dstack/_internal/core/services/ssh/tunnel.py", line 204, in aopen
raise get_ssh_error(stderr)
dstack._internal.core.errors.SSHError: Connection closed by UNKNOWN port 65535
```
If the replica runs on the local backend, connect
directly to the container, without proxy jumping
through the shim host. Similar to workarounds in
`SSHAttach` and `runner_ssh_tunnel`.
