Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Remove the tenant and user created for tempest"
  - Remove the tenant and user created for tempest

    According to the module [1] in tempest to parse tempest.conf,
    the three params in session idenity are invalid:

    [identity]
    tenant_name = tempest
    username = tempest
    password = Tempest123!

    Then there is no need to create tenant and user before running
    tempest and refstack_defcore.
