HOME variable is empty in the hooks when push goes through the HTTP
related gitlab-shell!90 (closed) and https://gitlab.com/gitlab-org/gitlab-ce/issues/20977
Puppet will not work because of this and I suppose it's needed for many cases.
I tried to set this variable in omnibus because this is unset there attributes/default.rb
but it's still empty in the hooks.
I'm not sure if this is workhorse issue or omnibus.
