Improve diff lines count efficiency

Creates new event when an epic is created, closed, reopened or
commented.

This fixes a high frequency N+1 issue:

`RoutableActions#find_routable!` is used across many controllers to
retrieve e.g. the Project or Namespace by path. The `#find_routable!`
method calls `#ensure_canonical_path` which in turn retrieves
`#full_path` from the given Routable.

This in turn triggers a lookup on `routes`, leading to a high frequency
of these queries:

```sql
SELECT  "routes".* FROM "routes" WHERE "routes"."source_id" = $1 AND
"routes"."source_type" = $2 LIMIT $3
```

This is unnecessary as we already join `routes` in
`Routable#find_by_full_path` anyways.

Modified schema via migrations.
Added one-to-one relationship between the two models.
Added changelog file

This commit adds pipeline.type key to PipelineEntity.
This key will be used in MR widget in the next iteration.

It performs an expensive operation, but isn't required in
most of tests

When updating group and project members, new system hooks
`user_update_for_group` and `user_update_for_team` will be executed.

Fixes https://gitlab.com/gitlab-org/gitlab-ee/issues/12252

This commit removes one RuboCop offense from its todo file.

Before this commit we redefined properties for supported events on each
new instance of ChatNotificationService during "runtime".

This commit defines the properties only once during "compile time".

This change limits the number of emails
for new access requests notifications to
10 most recently active owners/maintainers

This is to accomodate prepended modules.

This does not support upgrading from earlier versions

We should see the ratio drop down when enabling the Feature.

Recommendation by @andrewn

In order to lookup a Project or Namespace by path, we prefer an exact
match (case-sensitive) but in absence of that, we'd also take a
case-insensitive match.

The case-insensitive matching with preference for the exact match is a
bit more involved in SQL as the exact lookup. Yet, the majority of cases
will be an exact match. The thinking here is that we can optimize the
lookup by performing an exact match first and only if there is no
result, we perform the case-insensitive lookup.

Data for GitLab.com:
* We have about 15M records in routes table
* About 2,500 routes exist where there's more than one record
  with the same `lower(path)`

It is possible for a user to craft requests that would always trigger
the 2-step search (e.g. we have a route for `/foo/bar`, the request is
always for `/FOO/bar`). In this case, the change at hand is not
beneficial as it would run an additional query.

However, based on the data, it is highly likely that the vast majority
of requests can be satisfied with an exact match only.

The context for this change is
https://gitlab.com/gitlab-org/gitlab-ce/issues/64590#note_208156463.

This reverts commit 0eff75fa.

This improves the output produced when running an unknown command,
running the "help" command, and when trying to run a command you are not
allowed to run. The new help output includes links to the project of the
chatops integration, and a link to the chatops documentation.

Persists if a board list is collapsed for each user.

A new param with_security_reports was added to
GET /groups/:id/projects API and the code to
support this logic in GroupProjectsFinder and
Project model. Also, a DB index was added to
ci_job_artifacts table to speed up the search
of security reports artifacts for projects

When a issue is moved from one project to another, all associated
Markdown text is rewritten in the context of the new project. If the
note contained a link to a commit URL, `CommitRewriter#rewrite` would
fail because `Commit#link_reference_pattern` would match `nil` `commit`
values in the HTML generated from the Markdown. These `nil` values were
passed along to `Project#commits_by` because `Commit#reference_valid?`
was always returning `true`.

To prevent this issue from happening, we tighten up the check for
`Commit#reference_valid?` to look for valid SHA values.

totalNotes is only used to prerender a number of
skeleton containers until real notes are loaded

issuable.discussions makes multiple requests, so
too expensive for this

This commit uses mere notes for this and sends
actual totalNotes number if it's less than 10;
otherwise it sends 10 - it allows us to avoid
bunch of skeleton prerenderings, which are not
necessary since they doesn't fit into the whole
screen and disappear quite fast

Only displays the todo body if the todo has a note.
This is to avoid redundant Issue or Merge Request titles
displayed both in the Todo title and body.

During a project import, `LfsLinkService` attempts to link `LfsObjects`
that have not already been associated with a project.  It's possible for
a large repo to have thousands of OIDs, which can cause long database
query and parsing times.  By processing a batch of 1000 at a time, we
can reduce that time at the expense of a few more SQL queries.

Removed unused method for name setter method

The flag defaulted to true, so there's no change unless users turned it
off. Given there's a lack of issues regarding object pools, this should
be OK.

User images and videos will get proxied through
the Camo server in order to keep malicious
sites from collecting the IP address of users.

- Introducting StageEvents to define the available events
- Define the event pairing rules, since some events are not compatible
- Express default Cycle Analytics stages with the event structure

Increase sort options for issues list from updated_at and create_at,
to include more options close to what is required in actual issue list
UI.

This helps us to use REST API for issues list with sorting capabilities

Root namespaces have storage statistics.
This commit allows namespace owners to get those stats via GraphQL
queries like the following one

{
  namespace(fullPath: "a_namespace_path") {
    rootStorageStatistics {
      storageSize
      repositorySize
      lfsObjectsSize
      buildArtifactsSize
      packagesSize
      wikiSize
    }
  }
