staging infra: New vlan

Following documentation at [1], send an email to sesi [2] asking for it:

• 1 new vlan
• 1 public IP address (will be used for a SSH front-end/router to that VLAN)
• open ports for that IP address: http, https, ssh
• our hypervisors need access to that vlan:
  • swh5.inria.fr (beaubourg)
  • swh6.inria.fr (orsay)
  • swh8.inria.fr (hypervisor3)
• the ip 128.93.193.29 needs access as well (vm pergamon).
