Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to a2b459b347fb8c14944ee333e5f78daec89ac503
  - Merge "Add VFC env about reg_to_msb_when_start to determine whether register to microserice"
  - Add VFC env about reg_to_msb_when_start to determine whether register to microserice

    Becaue now oom can register the microservice to msb automatically,
    if without K8S, we can also register vfc microservice to msb
    automatically by vfc container itself.

    IF it is set to false, vfc contanier will not register again, if it is
    set to true, vfc will register by itself.
    we use this flag to determine who is responbile for serice registeration
    and it can reduce duplicate registration.
