• Unclear what users should configure/check in the Drain Cleaner Webhook configuration section(1)
• Users are contacting out technical support because they don't know what specific actions to take in this section's configuration.
• I found it unclear whether this section was explaining the internal behavior of the Drain Cleaner webhook or prompting users to change their certificate or permission settings.
• If my understanding is correct, almost all OpenShift users don't need to change ValidatingWebhookConfiguration.
• If we are prompting users to change any specific settings, please provide detailed instructions.
