Update git submodules

* Update docs/submodules/pharos from branch 'stable/euphrates'
  - Merge "config/pod1.yaml: Typo fixes, add 3 new nodes" into stable/euphrates
  - config/pod1.yaml: Typo fixes, add 3 new nodes

    In order to be able to check the PDF template against the current
    installer adapters, we need to fill in all 5 nodes info.

    While at it, perform some cleanup:
    - s/remoteparas/remote_paramsg/ (installers use this directly ...);
    - s/remote_mangement/remote_management/g;
    - s/pod owner/pod_owner/;
    - minor typo fixes;
    - fixed one IP overlap between 2 existing nodes;

    NOTE: Data for the 3 new nodes is bogus (random MACs, addresses).
