Remove the "soon to be deprecated" `alias_method_chain` in favor of `Module#prepend`.

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

Double check whether the behavior of `attr_encrypted_no_db_connection` is still the desired one.

## Why was this MR needed?

The `alias_method_chain` becomes deprecated in Rails 5 in favor of the `Module#prepend` introduced in Ruby 2.0.

This MR prevents future deprecated warnings in light of a possible Rails version bump.

Closes #22302

Take filters in account in issuable counters

## What does this MR do?

This merge request ensure we display issuable counters that take in account all the selected filters, solving #15356.

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

There was an issue (#22414) in the original implementation (!4960) when more than one label was selected because calling `#count` when the ActiveRecordRelation contains a `.group` returns an OrderedHash. This merge request relies on [how Kaminari handle this case](https://github.com/amatsuda/kaminari/blob/master/lib/kaminari/models/active_record_relation_methods.rb#L24-L30).

A few things to note:
- The `COUNT` query issued by Kaminari for the pagination is now cached because it's already run by `ApplicationHelper#state_filters_text_for`, so in the end we issue one less SQL query than before;
- In the case when more than one label are selected, the `COUNT` queries return an OrderedHash in the form `{ ISSUABLE_ID => COUNT_OF_SELECTED_FILTERS }` on which `#count` is called: this drawback is already in place (for instance when loading https://gitlab.com/gitlab-org/gitlab-ce/issues?scope=all&state=all&utf8=%E2%9C%93&label_name%5B%5D=bug&label_name%5B%5D=regression) since that's how Kaminari solves this, **the difference is that now we do that two more times for the two states that are not currently selected**. I will let the ~Performance team decide if that's something acceptable or not, otherwise we will have to find another solution...
- The queries that count the # of issuable are a bit more complex than before, from:

    ```
   (0.6ms)  SELECT COUNT(*) FROM "issues" WHERE "issues"."deleted_at" IS NULL AND "issues"."project_id" = $1 AND ("issues"."state" IN ('opened','reopened'))  [["project_id", 2]]
   (0.2ms)  SELECT COUNT(*) FROM "issues" WHERE "issues"."deleted_at" IS NULL AND "issues"."project_id" = $1 AND ("issues"."state" IN ('closed'))  [["project_id", 2]]
   (0.2ms)  SELECT COUNT(*) FROM "issues" WHERE "issues"."deleted_at" IS NULL AND "issues"."project_id" = $1  [["project_id", 2]]
    ```

    to

    ```
   (0.7ms)  SELECT COUNT(*) AS count_all, "issues"."id" AS issues_id FROM "issues" INNER JOIN "label_links" ON "label_links"."target_id" = "issues"."id" AND "label_links"."target_type" = $1 INNER JOIN "labels" ON "labels"."id" = "label_links"."label_id" WHERE "issues"."deleted_at" IS NULL AND ("issues"."state" IN ('opened','reopened')) AND "issues"."project_id" = 2 AND "labels"."title" IN ('bug', 'discussion') AND "labels"."project_id" = 2 GROUP BY "issues"."id" HAVING COUNT(DISTINCT labels.title) = 2  [["target_type", "Issue"]]
   (0.5ms)  SELECT COUNT(*) AS count_all, "issues"."id" AS issues_id FROM "issues" INNER JOIN "label_links" ON "label_links"."target_id" = "issues"."id" AND "label_links"."target_type" = $1 INNER JOIN "labels" ON "labels"."id" = "label_links"."label_id" WHERE "issues"."deleted_at" IS NULL AND ("issues"."state" IN ('closed')) AND "issues"."project_id" = 2 AND "labels"."title" IN ('bug', 'discussion') AND "labels"."project_id" = 2 GROUP BY "issues"."id" HAVING COUNT(DISTINCT labels.title) = 2  [["target_type", "Issue"]]
   (0.5ms)  SELECT COUNT(*) AS count_all, "issues"."id" AS issues_id FROM "issues" INNER JOIN "label_links" ON "label_links"."target_id" = "issues"."id" AND "label_links"."target_type" = $1 INNER JOIN "labels" ON "labels"."id" = "label_links"."label_id" WHERE "issues"."deleted_at" IS NULL AND "issues"."project_id" = 2 AND "labels"."title" IN ('bug', 'discussion') AND "labels"."project_id" = 2 GROUP BY "issues"."id" HAVING COUNT(DISTINCT labels.title) = 2  [["target_type", "Issue"]]
    ```
- We could cache the counters for a few minutes? The key could be `PROJECT_ID-ISSUABLE_TYPE-PARAMS`.

A few possible arguments in favor of "it's an acceptable solution":
- most of the time people filter with a single label => no performance problem here
- when filtering with more than one label, usually the result set is reduced, limiting the performance issues

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

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

We wanted to avoid accesses to the file system, because it seems reasonable that if the mounter column has some content it’s because there are an associate file. This is an speed boost when you access to a bunch of build instances to show their information.

The problem is that solution doesn’t work if you uses that method to detect the thing and you’re changing the uploaded file on instances that had that column empty. Until you don’t persist the instance the database column will be empty so we can have false negatives
