Bug: Couldn't get metrics ..., exception 'str' object has no attribute 'items'

[afcollins]

If an aggregated metric has a "not" section (example [1]), we will see an error[2].

[1]:

    - name: monitoringCPU
      metricName : containerCPU
      labels.namespace.keyword: openshift-monitoring
      metric_of_interest: value
      not:

I think I already found the source, and will raise a fixing PR shortly.
