Update git submodules

Update git submodules

* Update docs/submodules/integration.git from branch 'master'
  to a722a85525a880077b9df91f75e6c62d060d7c17
  - Merge "User first node for port scanning instead of last one"
  - User first node for port scanning instead of last one

    It is more obvious to use first node in cluster instead of
    last one. Additionally in some cases nodes listed in the end
    may not expose all open ports (like it is in integration lab).
