[QA] CI labs slaves no more use NFS

[Antoine Musso]

Hello,

Following the overnight labs NFS outage, the CI Jenkins slaves in labs
no more uses NFS.

So /data/project is gone, we never used it anyway.

Homedirs are now local to the instance. If you want your favourite dotfiles:

 operations/puppet.git
 ./modules/admin/files/home/<your username/...
