Don't drop in DropAndReaddHasExternalWikiInProjects

## What does this MR do?

This MR fixes the migration in question so it doesn't first drop and then re-add a column.

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

Not really.

## Why was this MR needed?

The old migration could lead to application errors as the column would temporarily not exist between the drop column and add column statements.

## What are the relevant issue numbers?

Add allow_failure CI documentation

## What does this MR do?

Adds documentation for the `allow_failure` keyword for the CI.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/17669

Add hints for Kerberos sign-in failure

We do not know what went wrong when this page is shown but we can guess.

See merge request !583

Dropping a column and then re-adding it can lead to the application
throwing errors as the column may temporarily not exist. To work around
this we'll reset the various project rows in batches _without_ removing
any columns.

Don't use `params[:id]` while building `markdown_preview_path`.

- Closes #20079

Merge branch '799-viewing-a-mr-with-approvals-with-an-anonymous-user-results-in-error-500' into 'master'

Don't check if anonymous user can update MR

Closes #799. Interestingly, I think previously we showed the 'Approve MR' button to anonymous users when an MR had approvals from anyone allowed, but we didn't blow up with a 500 error.

See merge request !582

1. Instead, use `@page.title`, since it's always guaranteed to be around
   in a wiki.

2. `params[:id]` is _not_ always guaranteed to be around - if a page is
    created with errors, `render :edit` is called, and `params[:id]` is
    `nil`.

3. More context: https://gitlab.com/gitlab-org/gitlab-ce/issues/20079#note_13223240

Fix migration to make it fast

## What does this MR do?

Changing the migration introduced in !5387 so that it's fast. The idea is that the content of the `projects.has_external_wiki` is currently wrong, so we can just drop and recreate the column.
