Review comment:
How about changing this function to
```python
def create_nodegroup(
self,
clusterName: str,
nodegroupName: str,
subnets: List[str],
nodeRole: str,
*,
tags: Optional[dict] = None
**kwargs,
) -> Dict:
...
if tags is not None:
resolved_tags = tags
else:
resolved_tags = {}
resolved_tags[f'kubernetes.io/cluster/{clusterName}'] = 'owned'
```
to better leverage Python’s built-in syntax. The `kwargs.pop()` or `if key
in kwargs` pattern was a pragmatic workaround on Python 2, but now that
keyword-only arguments are available, they make the API both easier to read and
write.
