Fix broken link in HA docs

Whoops! Fix broken link in docs from gitlab-org/gitlab-ce!3579

See merge request !3890

Updated HA docs and open to public

Closes https://dev.gitlab.org/gitlab/organization/issues/624

We still need to go through the old gitlab.com/standard/high-availability and move relevant docs over, plus do some docs on DRBD. However, I think this is a good volume for the first pass. Can we get this out there and then iterate?

cc/ @axil @patricio For your review, please.

Refactor Todos feature spec to be faster and less brittle

We now only create two Todos instead of 21 when testing pagination, and
we've updated the test to be less brittle when dealing with slower CI
environments.

Move cherry-pick feature specs to proper directory

Cherry pick feature specs were located in `spec/feature/project` directory while we have `spec/feature/projects`.

Later location is consistent with our namespaces (we have `Projects::` namespace, not `Project::`).

Always read diff_view setting from the cookie

Prior, when the user had their view set to "parallel" and then visited a
merge request's changes tab _without_ passing the `view` parameter via
query string, the view would be parallel but the `Notes` class was
always instantiated with the default value from `diff_view` ("inline"),
resulting in broken markup when the form to add a line note was
dynamically inserted.

The cookie is set whenever the view is changed, so this value should
always be up-to-date.

Fix vulnerability that leaks private labels and milestones

## Summary

This fixes vulnerability that leaks information about private labels and milestones because of  insecure direct object reference in issueable create service.
This affects merge requests and issues.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/15439

## Fix

This MR introduces additional check that rejects labels and milestone that does not belong to the same project issue/merg request does.

## Further work

`IssuableBaseService` may benefit from encapsulating filters in separate class/module, which then may improve coherency in this class.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15439

See merge request !1954

This also verify if milestone belongs to correct project before creating
a new issue.

Fixes text color on labels in sidebar

Previously the labels in the sidebar would just have `#FFF` text color which could cause problems with a light background color.

With this, the text color comes from the JSON.
