Update git submodules

* Update docs/submodules/pharos from branch 'stable/euphrates'
  - Merge "[fuel] cleanup: Drop infra_compute_*_address" into stable/euphrates
  - [fuel] cleanup: Drop infra_compute_*_address

    Our PDF installer adapter defines 3 unused reclass params that are
    misleading, so drop them (infra_compute_node{01,02,03}_address).
