Disable Sidekiq arguments logging by default

Some of the arguments passed to Sidekiq jobs are secret. With this
change we avoid logging those secrets, by turning off 'argument
logging' altogether.

Remove unused password argument

We no longer put a (random) password in the 'new user' email, so no need to pass it around in the code.

We were still passing a 'password' argument around, but it is not used
anywhere because we send a password reset link in the welcome email
nowadays.

Improve security release documentation

I think the MailChimp step is not needed anymore because we automated it.

Properly fix wiki restore

My previous patch didn't fix the restore issue (!247).

ProjectWiki.new() creates a new wiki git repository, so any tries to bare clone a bundle fail. With this patch we remove the newly created wiki.git before restoring from the backup bundle.

\cc @jacobvosmaer @dzaporozhets are you ok with this solution/hack?

Reactivate highlight.js language autodetection

### What does this MR do?

This commit partly reverts commit 0d13abb1 to reactivate highlight.js language autodetection.

It does NOT revert the part that adds the `nohighlight` CSS-class for a predefined set of filenames (which was indeed the intended purpose of commit 0d13abb1).

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

Not particularly, the only effect of this blob_helper is to add a CSS class to the `<pre>` container of the blob, to control the way highlight.js performs its syntax highlighting. (see where this helper is called at https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/shared/_file_hljs.html.haml#L12).

However this merge request DOES change the way the syntax highlighting is done (by bringing it back to the situation before commit 0d13abb1 where highlight.js autodetected the language itself). So we can expect some new kind of syntax highlighting problems. However in this case, the issues should be forwarded to the upstream project (https://github.com/isagalaev/highlight.js).

### Why was this MR needed?

The main motivation behind this partial revert is that there is no point (IMHO) in using an "intelligent" syntax highlighter which is specifically designed to autodetect languages if it is to dictate (via the CSS class) the language to use solely based on the filename extension.

### What are the relevant issue numbers / Feature requests?

Issue #665 "HLJS language autodetection / syntax highlighting fails "

### Screenshots (If appropriate)

Make clear that the upgrader script does not update gitlab-shell

There are many cases where people end up with a broken update because they don't update gitlab-shell.

Sidekiq memory killer

This change adds an optional Sidekiq memory killer middleware that
will perform a graceful shutdown when the Sidekiq process is using
too much memory. When combined with a process supervision daemon
(such as Runit in omnibus-gitlab) this should provide Good Enough
handling of the Sidekiq memory leaks we are seeing.

The memory killer is off by default.
