Support redis socket and with password.

Hi everyone.

I tried to support redis socket and with password to gitlab-ce.

Check here.

https://gitlab.com/JironBach/gitlab-ce

And test server is running here.

http://git.mydns.jp/

You can sign in with

id: gitlab

pass: gitlabtest

Try it!

I changed structure of resque.yml as support password.

Check resque.yml.example.

The routes.rb modified as monkey patch.

May I throw the "Merge Request"?

If so, which branch to merge?
