Update git submodules

* Update docs/submodules/apex from branch 'master'
  - Allow common patches file

    This patch adds allowing for common patches that should be applied to
    every scenario to be included. It by default pulls in a file in the
    deploy directory 'common-patches.yaml', but can optionally be
    overridden.

    This patch also includes a patch upstream to fix OSCLI not working
    anymore due to breakage with the Cinder version in the overcloudrc.
