Document AES password encryption for featureUtility properties

[riyaaroraa]

Summary

The featureUtility commands reference page should document how to encrypt passwords using the securityUtility encode command with AES encryption before adding them to featureUtility.properties.

Background

• featureUtility accepts plain-text passwords in featureUtility.properties, but this is not recommended for security
• Print unencrypted password warning without verbose mode open-liberty#35200 (now merged) ensures the CWWKF1374E warning always prints when an unencrypted password is used
• Users need documentation on how to properly encrypt passwords using AES encryption

Changes Needed

Add a section to the featureUtility commands reference page explaining:

• How to use securityUtility encode --encoding=aes to encrypt passwords
• That the encrypted value should be used in featureUtility.properties
• What warning message (CWWKF1374E) users will see if they use unencrypted passwords
