    Stop platform pods from requesting CPU resources

    While running tests in the lab, calico-node and
    kube-sriov-device-plugin pods are requesting CPU resources.
    All platform pods are supposed to have no CPU resource requests
    as it messes up the reported CPU allocations and reduces the
    amount of CPU available to the customer applications

    The CPU request allocation for calico-node and
    kube-sriov-device-plugin containers have been changed
    to "0". This will implement no CPU requests for pods
    in the platform namespaces

    The kube-sriov-device-plugin pod CPU requests was modified in
    a SR-IOV enabled lab, to help verify that the code
    change was successful

    Test Plan:

    PASS: set calico-node requests to 0 local build VM
          the following command was executed:
          "kubectl describe node controller-0"
          --> command response:
              Non-terminated Pods:
              .......
              calico-node-kxbpl CPU requests: 0 (0%)

    PASS: set sriovdp-node requests to 0 on SR-IOV enabled lab
          the following command was executed:
          "kubectl describe node controller-0"
          --> command response:
              Non-terminated Pods:
              .......
              kube-sriov-device-plugin-amd64-p5s4g CPU requests: 0 (0%)
