Update git submodules

Update git submodules

* Update docs/submodules/oom/offline-installer.git from branch 'dublin'
  to 96a1b549c7de9497cb3543ed8d3331230844db9c
  - Adding public network config capability to oom

    This change was implemented in El-Alto, I see no chance
    in getting into OOM dublin branch therefore suggesting
    adding it into our patch file. Its required for
    automatic vFWCL test execution.

    Issue-ID: TEST-166
