Manage the audit ID early in the request handling logic so that it can
be used by different layers to improve correlation.
- If the caller does not specify a value for Audit-ID in the request
header, we generate a new audit ID
- If a user specified Audit-ID is too large, we truncate it
- We echo the Audit-ID value to the caller via the response
Header 'Audit-ID'
