      When using a hierarchy of pod templates that define the same environment variables on the same container, the resulting definition contains duplicate, instead of applying overrides.

      This results into an invalid pod definition, causing for instance the following stacktrace

      java.lang.IllegalStateException: Duplicate key EnvVar(name=JAVA_TOOL_OPTIONS, value=-Xmx1g, valueFrom=null, additionalProperties={})
