Add tcp-ns option for pasta network driver

Hi, I tried all combinations I could think of but could not figure out how to create a TCP namespace forwarding of a host port to the container. Specifically I want to add 3128 from the host to the container and with the following lines in `containers.conf` I got it working just fine:

```toml
[network]
pasta_options = ["-T", "3128:3128"]
```

However, I don't want to add this to all containers, so I tried things with podman-py to no success! The closest suggestion is available at https://github.com/containers/podman-py/issues/248#issuecomment-1463728689 however my attempts resulting in some permission errors which I did not debug further (since using `containers.conf` just worked).

```python
instance = podman_client.containers.create(
...
networks={"pasta": {}},
network_options={"pasta": ["tcp-ns=3128:3128"]},
...
)
```

More Ideas were things like `network_options={"pasta": ["T=3128:3128"]}` or even `network_options={"pasta": ["T", "3128:3128"]}`.

What is the right way?
