Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "[baremetal] Upgrade packages on kvm, cmp nodes too"
  - [baremetal] Upgrade packages on kvm, cmp nodes too

    MaaS installs a few packages via curtin, which don't get upgraded
    later, even if we add extra repos (it will be the case for novcp).
    Perform a package upgrade on all baremetal nodes, as it's also a
    good security practice.
