Update git submodules

* Update docs/submodules/snaps from branch 'master'
  - Added new configuration option for OpenStackVmInstance for cloud-init

    Added cloud_init_timeout to VM instance configuration to override the
    default timeout value hardcoded @ 120 seconds. This patch not only
    expands the default value to 300, but also allows the client to override
    this value as cloud-init can take quite some time depending on what is
    being requested.
