[chef] elff repo for chef

[Titov Alexander < >]

Hi!

Elff repository has been switched off today, but I'm using this repo
on most of my servers due to migration to 0.10 isn't finished. If you
have mirror for elff or contacts who can turn on elff on some time,
please let me know, because bootstrap process depends on this repo for
me.

Thank you.
