It turns out they are different:

    builds.success.latest.first

and

    builds.latest.success.first

If we put success first, that latest would also filter via success,
and which is what we want here.

Add reminder to not paste private SSH keys

## What does this MR do?

Just got the "How would you make GitLab better?" mail and thought that I could follow it.

This commit adds a short reminder to not paste the private part of an SSH key to the form where one can add SSH keys to one's account. I think that's an useful message, both for people who aren't that experienced yet and for people who are sleep-deprived. :-)

I decided to just list the most common key type, `ssh-rsa`. The full list of key types in the [CVS repository of OpenSSH](http://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/usr.bin/ssh/sshkey.c?rev=HEAD&content-type=text/plain) contains some types which I'd regard as a bit obscure. Mentioning all of those types would probably clutter the form too much. We could think about whether to list what is probably the second most common key type, namely `ssh-dss`. But note that this key type [seems to be deprecated](https://security.stackexchange.com/questions/5096/rsa-vs-dsa-for-ssh-authentication-keys).

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

I didn't actually test this one-line change.

## Why was this MR needed?

It's not, strictly speaking, needed, but could be considered a nice addition.

Remove slow migration and add fix to sanitize errors

Run bundle install and update Gemfile.lock

!5078 didn't update the `Gemfile.lock` even though it added some restrictions on gem versions, this fixes that.

Add blockquote fence syntax to Markdown

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/16564

Before Markdown rendering happens, this will transform this:

```
Let me quote this here email:

>>>
Dear friend,

How are you?

Greetings,

Me
>>>
```

Into this, saving me from having to prefix all of those lines with `>` manually when I copy some multiline text from another medium:

```
Let me quote this here email:

> Dear friend,
> 
> How are you?
> 
> Greetings,
> 
> Me
```

Re-use queries in reference parsers

This MR changes the reference parsing pipeline to cache queried objects and re-use them on subsequent runs. Data is cached in the `RequestStore` module so it's automatically flushed after a request.

Certain references are processed multiple times. For example, for every system note we check if it's a cross reference by getting the issues, MRs and commits it references. When redacting data we may end up querying these very same objects. By caching this we can quite drastically reduce timings and SQL query counts.
