* Update docs/submodules/auto from branch 'stable/fraser'
  - Merge "checked code logic for UC2-vim001 recovery time measurement" into stable/fraser
  - checked code logic for UC2-vim001 recovery time measurement

    JIRA: AUTO-38

    Leveraging new OpenStack SDK release 0.14, tested existing code for
    UC2/vif-001 (simulated VM failure), to verify that generic code for
    recovery time measurement works.

    Entered test code in placeholders for this test case: challenge start
    (suspend a VM), challenge stop (resume, although this was done
    outside (from Horizon), to simulate an ONAP-controlled recovery),
    test code (periodic status check, stop when VM is active again).
    Time was measured correctly, output files (.csv) were created
    successfully.

    This will allow to close Jira ticket 38.

    Next steps will be to interface with ONAP, to obtain VNF info
    (especially the ID of the corresponding OpenStack VMs), and perform
    the same measurement, which this time will be an actual recovery
    time, provided DCAE data collection, Policy and CLAMP have the
    proper configuration.
