HDDS-6603. Dynamically refresh debug operations for audit log

[symious]

What changes were proposed in this pull request?

In HDDS-6562, we introduced the feature to exclude specific operations for AuditLog.

But the usage in PROD cluster is not convenient, we need to update the config and restart service to enable the new configuration.

This ticket is to add a new servlet to refresh the configuration for AuditLog.

What is the link to the Apache JIRA

https://issues.apache.org/jira/browse/HDDS-6603

@adoroszlai @dineshchitlangia @arp7 @ferhui Could you help to review this PR?

@symious Can you add a testcase enabling debug operations dynamically? Correct me if I am wrong I dont see this in this PR.

[dineshchitlangia]

@symious The Audit Log implementation is done via log4j2 which supports dynamic refresh via the log4j2 configuration as shown below.
# Checks for config change periodically and reloads
monitorInterval=5

Check example log config file below:
HDDS/test/Auditlog.properties

Can you please add more details if you faced issue with audit log config change in production environment?
