Add LDAP maintenance task

I've received quite a few support requests where a user has renamed their LDAP server in the configuration file. This causes lots of issues where users are suddenly unable to sign in. It's easy enough to fix through the Rails console, but each time I had to instruct users how to get to the Rails console and what to type. This Rake task takes care of this and updates from old to new provider automatically.

Example: `sudo gitlab-rake gitlab:ldap:rename_provider[ldapmain,ldapcustom]`

cc/ @patricio @balameb Do you think this is useful?

Make CI badge hitboxes better match container

## What does this MR do?

Makes the Pipeline graph badge hitboxes accurately match their containers.
Currently, there's an issue where the badge highlights, as though, it's clickable, but clicking it does nothing:

![before](/uploads/668f841c640bc586044c89bed9f1e1e9/before.gif)

This is due to the `<a>` and `<button>` elements being padded into the parent elements. So, the parent would react to a cursor, but the cursor wouldn't be on the `<a>`/`<button>` yet.

![before-hitbox](/uploads/6ebaaa4be1096fbfc37f8d73da492c7b/before-hitbox.png)

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

Maybe the tests? I kept the style changes as minimal as possible.

## Why was this MR needed?

I was annoyed every time I clicked on a badge that I was _clearly on_ (it highlighted), but nothing happened.
If I found it irritating, perhaps someone else did too.

## Screenshots (if relevant)

How it behaves in the PR:
