Reviewed common logic, will do a second pass on the magic methods

nit: a bit repetitive, wdyt about starting with

condition = sample[self.SAMPLE_LABELS].get('condition')
if condition:

kubernetes_state/datadog_checks/kubernetes_state/kubernetes_state.py Outdated
label_value = self._extract_label_value('status', labels)
return label_value, switch.get(self._extract_label_value('condition', labels),

I'm concerned we might start throwing KeyErrors if the label were to miss. Shall we use get('condition') instead, to mimic _extract_label_value's return-None-if-not-found behaviour?
