Create 'Close Event Frame delay' setting

When you create PI Point Data Reference attributes in event frame templates that are used by PI Batch Interfaces, the PI Batch Interface will be responsible for resolving and capturing this PI Point data as soon as it closes the corresponding event frame. In some cases, data might arrive late to the PI Points that are referenced by these attributes due to issues like data bursts, disruptions or network latency; in such cases, the PI Batch Interface will capture inaccurate data when it closes the event frame, and you will need to manually recapture the attribute values using PI System Explorer or AFSDK to correct them. It would be useful to have the option to add a delay to when the interface closes its event frames, so that we can account for any potential tardiness in PI Point data that is referenced by these event frame attributes.
