bug: duplicate `securityContext` on confluence container in statefulset breaks helm chart install

Description

There is a duplicate securityContext on the confluence container in the stateful set. I'm noticing a lot of null values as well such as hostAliases, initContainers and a lot of the properties inside of the securityContexts are null. There's also a lot of whitespace which doesn't necessarily matter.

Steps to reproduce

1. git checkout 1.15.0-bb.4
2. cd chart
3. helm template --values values.yaml confluence .
4. see rendered StatefulSet
