The opc-request-id header returned by the service that should be provided for support
If the client timed out or failed to get a response from the service, then this is the
outbound request id, i.e. either the value for the BmcException.OPC_REQUEST_ID_HEADER
header set by the caller in an invocation callback, or otherwise a value automatically
generated by the SDK.
Flag to indicate that the exception originated from the client and not from the service.
Status code and service code should not be used if this is true.
