  - KVMFORNFV: Disabling daily job

    This patch is used to temporarily disable kvmfornfv daily job from
    triggering as Intel-pod10 is currently not available for executing
    daily test cases.

    Note: Will enable the kvmfornfv daily job once Intel-pod10
    is available for executing test cases.
