1. Make the "subscribed" text in Issuable sidebar reflect the labels
   subscription status

2. Current user mut be logged-in to toggle issue/MR/label subscription

1. Allow subscribing (the current user) to a label

- Refactor the `Subscription` coffeescript class
  - The main change is that it accepts a container, and conducts all
    DOM queries within its scope. We need this because the labels
    page has multiple instances of `Subscription` on the same page.

2. Creating an issue or MR with labels notifies users subscribed to those labels

- Label `has_many` subscribers through subscriptions.

3. Adding a label to an issue or MR notifies users subscribed to those labels

- This only applies to subscribers of the label that has just been
  added, not all labels for the issue.

Fix double borders around the CI status

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/14281
Introduced by https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/2760#note_4238291

See merge request !3224

The queries that are UNION'd together don't need any eager loading
(since we really only use the resulting SQL instead of having
ActiveRecord actually run the queries). By dropping any eager loaded
associations queries such as the following work instead of producing a
SQL error:

    Project.all.includes(:namespace).search('foo')

[ci skip]

Related to #2235.

This is done by:
1. Delaying the notification sending after the SSH key is commited in DB
2. Gracefully exit the mailer method if the record cannot be found

This solves the problem with caching the nil value with instance variable.
Without this the every time we ask for external_issue_tracker we built AR and potentially do SQL query

Remove allowed to fail by ignoring RedCloth

Having `Allowed to fail` jobs will only make sure we'll miss something
when it should fail, so I excluded a known issue which has been an
issue a long time now.

Now when this build is not green we know we should look at it and pay
attention.

New CI YAML features

This introduces a couple of small `.gitlab-ci.yml` features:

1. Documentation for: Allow to use YAML anchors when parsing the `.gitlab-ci.yml`: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/2958
2. Ignore jobs that start with `.`
3. Allow to pass name of created artifacts archive in `.gitlab-ci.yml`
4. Allow to define on which builds the current one depends on

These are really small changes so it makes not sense to create a separate merge requests for them.

@axil Could you review the documentation part?
