De-containerify uffizi

uffizi (the main storage backend and objstorage server) should move to the bare metal that currently hosts the louvre hypervisor, removing the containerization layer and giving it all the ram of the host.

on the container :

• install a kernel, install grub
• install lvm2, multipath, mdadm
• pull lvm2, multipath, mdadm config from louvre
• write /etc/fstab
• install ifenslave, vlan
• pull network config (bond, vlan, storage array management) from louvre and adapt to use uffizi ip address
• pull the hand-installed storage array management tools from /opt on louvre

on the infra:

• stop workers

on the host:

• stop the container
• chroot in the container rootfs and run grub install
• reboot
