Kerberos require to stable 7.12

If kerberos is enabled require it

Since 'group: :kerberos' got [included in the Gemfile ](https://gitlab.com/gitlab-org/gitlab-ce/commit/2391a43a7073b4e723e9ca1f7ff19b30f8e51452) Kerberos no longer got [loaded when the app started](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/application.rb#L6)

This caused `Devise::OmniAuth::StrategyNotFound` error once Kerberos is enabled, failing to start GitLab .

With this we hopefully do not need to remove group from the Gemfile.

Update install docs for 7.12

See merge request !1857

Even though the 7-12-stable branch does not exist yet.

Git 2.1.2 does not protect against pushes trying the '.Git/config'
attack (CVE-2014-9390). Going to 2.4.3 is perhaps a big jump but why not
use the latest? (Famous last words.)

Remove text since rss is now to prominent.

Fix link to howto_rc1.md

The relative link that was there before breaks when you copy-paste the
issue template into an actual issue.

Prepare feature steps for RSpec 3

See merge request !803

There's a naming conflict between Capybara and rspec-matchers which both
define the `all` method.

See https://github.com/jnicklas/capybara/issues/1396

Add a note that changing example configuration files requires changing omnibus-gitlab.

Keeping track of changes in these files is not easy and they usually require change in omnibus-gitlab.

Added a note so everyone is aware of this.

Similar is added to gitlab-shell and gitlab-ci.

Discussed in gitlab-org/omnibus-gitlab#605
