All other commands in the guide set this env var, but it's missing here
and this causes whenever not to clear the crontab file of gitab_ci
properly.

Link directly to the projects page instead of the root controller

If "Your Projects' Activity" dashboard setting were selected, it would be impossible to navigate to the projects page since the redirection would always bounce back to the activity dashboard.

Add support for AWS S3 Server-Side Encryption support

This adds support for AWS S3 SSE with S3 managed keys, this means the
data is encrypted at rest and the encryption is handled transparently to
the end user as well as in the AWS Console.

## Points to double check
I'm unsure on the best way to the handle the default. I've followed the `multipart_upload` de facto in the app. I'm happy to change this if required or if it will impact elsewhere e.g. omnibus packages

I also think I've managed to catch all of the documentation for this change as well.

### Why is this required
Many enterprises require good backup support but also for this to be encrypted. By default backups aren't encrypted, this allows at rest encryption to be supported in GitLab backups providing a layer of security should the physical media not be properly disposed of.

Relates to issue #2478.

Improve repo cleanup task

I accidentally wrote a new script, not seeing we already had one.
But the old one did not do enough (it only handled global namespace orhpans) so I figured I should just drop in the new script.

Remove 'kerberos' from auth_helper.rb for gitlab-CE.

There is no Kerberos auth in gitlab-ce, so it shouldn't be noted
as a form-driven auth mechanism in app/helpers/auth_helper.rb.
This breaks using Kerberos as a custom omniauth provider.
See issue #2510 (https://gitlab.com/gitlab-org/gitlab-ce/issues/2510).
