Use a ConnectionPool for Rails.cache on Sidekiq servers

## What does this MR do?

On Sidekiq server we'll use a connection pool to connect to the redis store used for Rails cache. But now we're sure we're not modifying the configuration used on the lazy create Redis connection inside the connection pools. I've create a PR on [redis-activesupport](https://github.com/pacoguzman/redis-activesupport) too. @jacobvosmaer-gitlab make this easier updating the Gitlab::Redis class !6472

Remove Flog

This MR removes the flog gem and its associated rake task as we use the ABC Metrics Rubocop to accomplish the same thing. There's not really any reason to have it anymore.

The rest of this MR is kept for posterity and is no longer relevant.

-------

After a few months of flog/flay failing silently - and now a week of them failing loudly - I think it's safe to say we don't care enough about flog/flay for them to be worth keeping.

If you'd like to keep them around, speak now or forever hold your peace :)

Do not regenerate the `lfs_token` every time `git-lfs-authenticate` is called

## What does this MR do?

 Do not regenerate the `lfs_token` every time `git-lfs-authenticate` is called, instead return the saved token if one is present.

This was causing a lot of 401s, leading to 403s, as state in #22527

As it turns out, when pushing a lot of LFS objects, the LFS client was calling `git-lfs-authenticate` in the middle of the request again. This caused the `lfs_token` to be regenerated. The problem lies in that the LFS client was not aware of this change, and was still using the old token. This caused all subsequent requests to fail with a 401 error.

Since HTTP Auth is protected by Rack Attack, this 401s where immediately flagged and resulted in the IP of the user being banned. 

With this change, GitLab returns the value stored in Redis, if one is present, thus if the LFS client calls `git-lfs-authenticate` again during the request, the auth header will remain unchanged, allowing all subsequent requests to continue without issues.

Fixes #22527
