* Update docs/submodules/kvmfornfv from branch 'master'
  - Disabling execution of cyclictest as part of verify job.

    This patch is used to temporarily disable cyclictest execution as a part of
    kvmfornfv verify job to speed up the verification process.

    This is only a temporary workaround/solution as kvmfornfv verify job
    is getting triggered for patches which includes only docs/ as well.

    Note: Once complete documentation is made available for danube release
    will revert this patch
