This MR fixes a bug that unnecessary escapes reserved HTML characters for Milestone's title.  See #22452. 

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

- Unescaping of sanitized milestone title before it is being stored in the database. See `Milestone#title` and a private method called `Milestone#sanitize_title`
- Sufficient tests were added (Model and API tests were modified/added).

## Why was this MR needed?

To allow reserved HTML characters in a milestone's title, such as "PHP migration 5.6 -> 7.0". The text appears in 'milestones' and in a dropdown during issue creation, issue list, and in another dropdown for issue filter. 

Closes #22452

See merge request !6533

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).

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 :)
