Add helm-unittest tests for revisionHistoryLimit:
- Default value (3) verification
- Custom values support (0, 1, 5, 100)
- Ability to disable revision history
Add NOTES.txt with revisionHistoryLimit information:
- Show configured revision history limit
- Warning when disabled (0)
- Note for minimal history (1)
- Rollback command example for normal values
This parameter controls how many old ReplicaSets are retained
for rollback purposes, reducing etcd storage usage.
