Review comment:
So if a user passes a custom configMap that just contains a log4j.xml,
the operator will still create a configMap for the xml, correct?

Review comment:
So if the custom configMap contains both a Solr.xml and a log4j.xml,
then this will add 2 volumes, using the same configMap, correct?
Is this supported in Kube? I think there might be an issue. But if you've
tested it, then maybe it's ok to go.
It would be pretty easy to make sure that the volume is only added once, and
it has the correct `items`.
