How to flushAll while using a createCluster instance

[egmzy]

Description

I'm using createCluster as a client instance to run commands like GET and SET.

const client: RedisClusterType = createCluster(options)

I want to implement a deleteAllKeys function but RedisClusterType doesn't have FLUSHALL.

async deleteAllKeys() {
    return await client.FLUSHALL();
}

The only Info I could find is here in the docs:
https://github.com/redis/node-redis/blob/HEAD/docs/clustering.md

It mentions getSlotMaster() but no explanation on how to use it.
Also the code says it's deprecated and we should use slots() instead, which I couldn't find docs for.

Any idea on how I can approach this?

Until #2431 will be implemented, you can use this to run FLUSHALL on all masters:

await Promise.all(
  cluster.masters.map(async master => {
    await (await cluster.nodeClient(master)).flushAll();
  });
);

client.slots - if you want to get the client of a specific slot
client.shards - if you want to work on a "per shard" (master + it's replicas) basis.
client.masters - just the masters
client.replicas - just the replicas

we definitely need to update the docs..
