Add helm-unittest tests for init containers: - No init containers by default - extraInitContainers support (single and multiple) - Full container spec preservation (command, args, volumeMounts, securityContext) - Backward compatibility with deprecated initContainers parameter - Merging of initContainers and extraInitContainers - Correct ordering when both are specified Add NOTES.txt with init containers information: - Show count of configured init containers - Deprecation warning when old initContainers parameter is used - Migration guidance to extraInitContainers This fixes the critical bug where extraInitContainers didn't work and provides clear migration path from deprecated initContainers.
