Closes todos for a merge request when the MR is accepted via the API by the MR assignee.

## Are there points in the code the reviewer needs to double check?

Please review refresh service test changes to see if they are correct - I think in those cases, the todos should actually be cleared instead of left pending.

## Why was this MR needed?

To make the API behavior consistent with the UI behavior (accepting your own MRs closes the todo item and prevents them from piling up).

Closes #22477

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

Closes #22364

Expose pipeline data in builds API

Closes #22367

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 :)
