What would you like to be added?

I would like to add compact, get_compaction_state, flush and get_server_version in MilvusClient.

 def flush(
        self,
        collection_name: str,
        timeout: Optional[float] = None,
        **kwargs):
        pass
        
 
def compact(
        self,
        collection_name: str,
        is_clustering: Optional[bool] = False,
        timeout: Optional[float] = None,
        **kwargs,
    ) -> int:
    return job_id


def get_compaction_state(
        self,
        job_id: int,
        timeout: Optional[float] = None,
        **kwargs,
    ) -> str:
    """
       Possible values are "UndefiedState", "Executing" and "Completed".
    """
    return ""
 
def get_server_version(
        self,
        timeout: Optional[float] = None,
        **kwargs,
    ) -> str:
    return ""

Why is this needed?

sync with Collection(orm).

Anything else?
