LGTM

In the Kubernetes environment, I couldn't inject MASTER_SERVER_LOAD_PROTECTION_MAX_JVM_MEMORY_USAGE_PERCENTAGE_THRESHOLDS intomaxJVMMemoryUsagePercentageThresholds as configured. However, modifying it tomaxJvmMemoryUsagePercentageThresholds does allow successful injection. I suspect this might be related to the getters and setters generated by Lombok.
