Update git submodules

* Update openstack-ansible from branch 'master'
  to 48c523645fd4d40e2349100a091c3d4d2101dead
  - Merge "Ensure bash-completion also search for .yaml"
  - Ensure bash-completion also search for .yaml

    extension, which might be a good chunk of third-party playbooks.

    Let's ensure we cover them as well.
