Enable a way to set non-persistent attributes in outbound processing classes only when they're requested

In a lot of the outbound definition classes, additional MboSets are established to set a non-persistent field. These should ideally be done via attribute field classes on the non-persistent attribute(s) instead of depending on the outbound definition class. But if we at least enabled a more efficient method in the outbound definition classes, then we can minimize the impact.

For example, the asset outbound processing class (psdi.iface.app.asset.MoutAssetProcess) sets hierarchypath in the checkBusinessRules using mbo.getString("CLASSSTRUCTURE.HIERARCHYPATH"). This requires for every asset record we are establishing a new set to get the hierarchy path even if we don't need that data. For example, in the REST API if we are only retrieving the assetnum & description field. And even in the scenario that we want hierarchy path, this prevents us from being able to utilize the REST API caching mechanism. This can negatively impact performance, especially during bulk downloads like Maximo Mobile.

In addition to Asset, the Item (MoutItemProcess), Job Plan (MoutJPProcess), Locations (MoutOperLocProcess), and likely others set the hierarchy path.

There are other examples as well. For example, multiple inventory outbound definition classes (MoutInvBalancesProcess, MoutInvProcess, MoutRSVProcess, MoutInvVendorProcess, etc.) set the ITEMTYPE field.

If setting these attributes could be moved out of the checkBusinessRules and put into a method that only sets these fields when they are being requested, we can minimize the performance impact when they're not needed.
