Update git submodules

* Update docs/submodules/functest from branch 'stable/euphrates'
  - Live migration support determination in rally

    Live migration test cases were excluded if tempest was not executed
    before rally since tempest config file is created during the execution
    of tempest.

    Remove the dependency to config file and define the support based on
    the number of computes as done in tempest.
