Document security implications

When writing documentation that involves handling sensitive data or security-related operations, always include explicit warnings about security implications and provide references to security best practices. Users may not be aware of default security behaviors that could expose sensitive information.

For example, when documenting the creation of Kubernetes Secrets, include a warning that Secrets are unencrypted by default:

kubectl create secret generic ufm-credentials \
  --from-literal=username='your-ufm-username' \
  --from-literal=password='your-ufm-password' \
  -n volcano-system

Warning: Secrets are still unencrypted by default. If users need to encrypt Secrets, please refer to: https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/

This practice helps users make informed security decisions and prevents accidental exposure of sensitive data due to lack of awareness about default security configurations.
