Feature: Adds support for the Redis cluster

[powersemmi]

Is your feature request related to a problem? Please describe.
We use redis cluster at our company, but there is no cluster mode support in faststream. When trying to connect to one of the nodes and send a message, faststream displays an error

redis.exceptions.ResponseError: MOVED 7304 127.0.0.1:1234

Describe the solution you'd like
I would like to get support for redis cluster mode. And specifically:

1. I am most interested in working with redis streams from cluster mode, so it would be cool if you added a RedisClusterBroker that would take as an argument a list of connections to clusters
2. The method of sending a message must correctly distribute messages across clusters (you can read about this in the redis documentation) and have a parameter for the name of the consumer group when the "stream" parameter is specified
3. The consumer must create a stream in the cluster and correctly receive messages from different nodes

I experimented a bit and came to the conclusion that the following solution will solve the problem

from typing import Any

from faststream.redis.broker import RedisBroker
from faststream.redis.producer import RedisFastProducer
from faststream.redis.security import parse_security
from faststream.types import AnyDict
from redis.asyncio.cluster import RedisCluster as Redis
from redis.asyncio.connection import parse_url
from typing_extensions import override


class RedisClusterBroker(RedisBroker):
    @override
    async def _connect(  # type: ignore[override]
        self,
        url: str,
        **kwargs: Any,
    ) -> 'Redis[bytes]':
        url_options: AnyDict = parse_url(url)
        url_options.update(kwargs)
        url_options.update(parse_security(self.security))

        client = Redis.from_url(url=self.url)
        self._producer = RedisFastProducer(
            connection=client,
            parser=self._global_parser,  # type: ignore[arg-type]
            decoder=self._global_parser,  # type: ignore[arg-type]
        )
        return client

But in order to be able to fully use the arguments of the RedisCluster class, you need to make a few more changes. Maybe one of these days I'll create an MR with everything I need.
