feat(sdk): without Some in _opts functions

Option has been removed as a wrapper around opts. This makes it much
more convenient to use

```rust
client.container_opts(Some(ContainerOpts{}))
// ->
client.container_opts(ContainerOpts{})
```

The same options are still available, either an empty object can be
passed, or a non _opts function can be used
