Feature Request: Pooling

Add a Option when creating a Redis for: pool: { min: number = 10, max: number = 250 }

This increases production, not having to code it manually with e.g. https://npmjs.org/generic-pool

It would just add a couple functions in all execution methods:

// example:
async function executeRedisCommand(method, ...extras) {
  const clientOfPool = await redis.pool.acquire();
  const res = clientOfPool[method](...extras);
  await redis.pool.release(conn);
  return res;
}

Thanks!
