Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Merge "Enhancements to the SNAPS orchestrator/launcher"
  - Enhancements to the SNAPS orchestrator/launcher

    Added support for more Ansible substitution values extracted
    from OpenStack instances (i.e. subnet broadcast address, router
    external IP for gateway configuration, CIDR IP, netmask, etc.)

    Removed most try/except blocks to ensure processing does not
    continue when a problem should arise

    Added the ability to know when cloud-init has completed

    Removed nic configuration from OpenStackVmInstance as userdata/
    cloud-init/cloud-config should be performing that functionality

    Fixed some logging messages

    Misc launcher bug fixes
