Feature request

RedisChatMessageHistory should have redis_client as argument

Motivation

I want to use RedisChatMessageHistory with mTLS.

Proposal (If applicable)

def __init__(
    self,
    session_id: str,
    redis_client: None,
    url: str = "redis://localhost:6379/0",
    key_prefix: str = "message_store:",
    ttl: Optional[int] = None,
):
    try:
        import redis
    except ImportError:
        raise ImportError(
            "Could not import redis python package. "
            "Please install it with `pip install redis`."
        )

    try:
        if redis_client is not None:
            self.redis_client = redis_client
        else:
            self.redis_client = get_client(redis_url=url)
    except redis.exceptions.ConnectionError as error:
        logger.error(error)

    ...
