Gather historical pod list from Elasticsearch
What does this MR do?
Issue: #196191 (closed)
Allows the user to select pods that have been terminated and for which log data still exists in Elasticsearch's index. The kubernetes API only returns running pods, so we switch to querying ES for the pod list.
This is limited to the 500 most verbose pods. In the future we will need to make the pod dropdown searchable to allow for all pods to be queried. We might also want to display the number of log lines next to the pod.
Similarly, pod containers are limited to 500, although these are mostly in the single digits so it shouldn't be an issue. (we also don't expose containers in the UI yet)
