add slack notifications for wiki pages

## What does this MR do?

Lets the Slack service be configured to send notifications when wiki pages are created or edited.

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

I'm just starting to get familiar with the Gitlab codebase and I was unsure on how to get the wiki page url to pass it to the slack message, on whether or not I needed to refactor the create/update methods for wiki pages from the controller to a service (but seemed necessary to test it better), and if I needed to add a column to the web hooks table or if the services table would have been enough. Please let me know if I should change anything and I will improve the MR, thanks for checking :)

## Why was this MR needed?

Related to #563 and fixes #4233.

Issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/12785
Merge Request: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3514

In doing this I'm breaking my own rules of not merging master into a
stable branch during the feature freeze. I'm breaking this rule for two
reasons:

1. Somewhere down the line I messed up picking commits into the stable
   branch and as a result I basically can't merge anything anymore
   without resolving 9000 merge conflicts.

2. All merge requests merged into master had the "Pick into Stable"
   label anyway except for one commit that bumps the version. As such
   merging master into this branch is not really different from picking
   things manually.

Sanitize branch names for confidential issues

- When creating new branches for confidential issues, prefer a branch name like `issue-15` to `some-sensitive-issue-title-15`.
- The behaviour for non-confidential issues stays the same.

Closes #14566

Configuring of points per UDP packet

Related to https://gitlab.com/gitlab-com/operations/issues/195. This option would allow us to experiment with finding a good balance between points-per-packet and the UDP packet size.

Bump version to 8.8.0-pre

See merge request !3809

"git lfs init" is deprecated, use "git lfs install" instead.

Recent releases of git-lfs warn that "init" is a deprecated command and that "install" should be used.

Remove persistent XSS vulnerability in `commit_person_link` helper

Because we were incorrectly supplying the tooltip title as
`data-original-title` (which Bootstrap's Tooltip JS automatically
applies based on the `title` attribute; we should never be setting it
directly), the value was being passed through as-is.

Instead, we should be supplying the normal `title` attribute and letting
Rails escape the value, which also negates the need for us to call
`sanitize` on it.

Removed aside toggle on profile pages

Trigger filtering after ajax is complete in dropdown

Closes #15186

See merge request !3813

This allows users to configure the number of points stored in a single
UDP packet. This in turn can be used to reduce the number of UDP packets
being sent at the cost of these packets being somewhat larger.

The default setting is 1 point per packet so nothing changes for
existing users.

API: Present an array of Gitlab::Git::Tag instead of array of rugged tags

The annotated message was always `null` because the wrong array was presented. 

The entity requires an array of `Gitlab::Git::Tags` instead an array of raw rugged tags was presented. Since a rugged tag does not respond to `message` to get the annotated message, this was always `null`.

Add notice about GitLab Runner to requirements docs

This is related to #14589, and problems that may stem from running
GitLab Runner on same machine user installed GitLab web app on.

* 'master' of dev.gitlab.org:gitlab/gitlabhq:
  Add Changelog entry for group link permissions fix
  Use guard clause to check ability to share project
  Refactor method that shares project with a group
  Check permissions when sharing project with group

Check permissions when sharing project with group

## Summary

Unprivileged user was able to share project with group he didn't have access to, and therefore gain partial access to that group, which opened possibilities for further actions like listing private projects in that group.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/15330

## Fix

This change introduces additional check for group read access.

## Further work

We can think about preventing such problems in the future (this is quite common problem) by moving permissions checks to another layer of abstraction (TBD).
