Update git submodules

* Update openstack-ansible from branch 'master'
  to 072a66673dbed0d0dd017f179b10b3b71ee9b62a
  - Merge "ci: add nova console log collection and fix build file collection"
  - ci: add nova console log collection and fix build file collection

    Bash wildcard expansion resulted in too many arguments to the
    store_artifacts function. This is remedied by passing in
    directories instead, with a wildcard filter for file types.

    The same approach is used to store nova VM console output
    without picking up disk images from the same directory.
