This PR supports copying files into the container before startup time:

```python
DockerContainer("alpine")
    .with_command(["cat", "/tmp/copied.txt"])
    .with_copy_into_container(src, "/tmp/copied.txt")
```

To support this, I had to change how the container is started: `run` is
not longer used, but instead `create` and `start` are used now, in order
to be able to make the `copy` before the container is actually running.

Inspired by testcontainers/testcontainers-rs#730
where I did exactly the same feature for the rust implementation of
testcontainers :)
