Update git submodules

* Update docs/submodules/fuel from branch 'stable/euphrates'
  - patches: pharos: Drop patches merged upstream
    
    Also, remove redundant pharos patch that adds prx mgmt IPs:
    - "Re-assign mgmt network to proxy nodes"
    as those values are set already (to different values!) by patch:
    + "extend public gateway support"
    
    While at it, `make patches-export` should clean the patch dir first.
