Zookeeper pod label customization not working

[endzyme]

Description

When trying to apply custom labels to Zookeeper pods through the SolrCloud spec, the labels do not show up on the final set of Zookeeper pods.

The issue appears to be that the Zookeeper Operator is not propagating the zookeepercluster.spec.pod.labels fields, but only applying labels which are defined in zookeepercluster.spec.labels.

Possible Solutions / Workarounds

Solution: Zookeeper Operator fixes the code to ensure the pod.labels are applied to the final StatefulSet for the Zookeeper ensemble.

Workaround: Change the Solr Operator to create the ZookeeperCluster custom resource to apply labels to zookeepercluster.spec.labels instead of zookeepercluster.spec.pod.labels.

Thanks for finding this issue!

This sounds like a good workaround, since it doesn't look like they will fix the issue soon.

Would you mind making a PR for this?

The Zookeeper Operator fix for this issue was released in v0.2.15.

Once #549 is complete, we can remove this workaround before it is released in v0.7.0.
