Update git submodules

* Update openstack-doc-tools from branch 'master'
  - Merge "Use unittest.mock instead of mock"
  - Use unittest.mock instead of mock
    
    The mock third party library was needed for mock support in py2
    runtimes. Since we now only support py36 and later, we can use the
    standard lib unittest.mock module instead.
