Pass CACHE_OPTIONS as kwargs to redis_from_url

[foarsitter]

This PR passes CACHE_OPTIONS as **kwargs to redis_from_url so complex option be can passed to redis client.

cache = Cache(
    config={
        "CACHE_TYPE": os.environ.get("CACHE_TYPE", "RedisCache"),
        "CACHE_REDIS_URL": redis_cache_url(),
        "CACHE_OPTIONS": {
            "retry": Retry(ExponentialBackoff(cap=2, base=1), 3),
            "retry_on_error": [ConnectionError, TimeoutError, ConnectionRefusedError, ConnectionResetError],
            "health_check_interval": 1,
        },
    }
)
