Infra investigation followup: RedisCache Client error
Summary
On 2023-05-11 we see an increase on redis_connected_clients which is saturating our maxclients for redis-cache. In https://gitlab.com/gitlab-com/gl-infra/chef-repo/-/merge_requests/3496 we increased the maxclients from 40k to 60k to prevent further saturation happening. We need to understand why we see an increase in redis_connected_clients to see if this a problem or just natural growth.
