Make sure the active phase status is retrieved for kubernetes pods in state_pod

[Crazybus]

For kube_pod_status_phase there are multiple metrics for each status phase with identical metric names but different phase labels. The test data only contained a single status phase so it was working perfectly, however when there are multiple status phases the code was always picking unknown for all pods in state_pod.

kube_pod_status_phase{namespace="test-namespace",phase="Failed",pod="test-pod"} 0
kube_pod_status_phase{namespace="test-namespace",phase="Pending",pod="test-pod"} 0
kube_pod_status_phase{namespace="test-namespace",phase="Running",pod="test-pod"} 0
kube_pod_status_phase{namespace="test-namespace",phase="Succeeded",pod="test-pod"} 1
kube_pod_status_phase{namespace="test-namespace",phase="Unknown",pod="test-pod"} 0

Oddly enough container_pod isn't affected by this since it does have seperate metrics per status phase

kube_pod_container_status_ready{container="test-container",namespace="test-namespace",pod="test-pod"} 0
kube_pod_container_status_restarts{container="test-container",namespace="test-namespace",pod="test-pod"} 0
kube_pod_container_status_running{container="test-container",namespace="test-namespace",pod="test-pod"} 0
kube_pod_container_status_terminated{container="test-container",namespace="test-namespace",pod="test-pod"} 1
kube_pod_container_status_waiting{container="test-container",namespace="test-namespace",pod="test-pod"} 0

Could you add a CHANGELOG entry?

[Crazybus]

@ruflin Added! Does it make sense for me to to add a note about adding a CHANGELOG entry to the beats contributing guide?

[ruflin]

@Crazybus Thanks. Yes that would be awesome.
