A way to troubleshoot error cases involving WRP messages

We recently ran into an error scenario in which it would have been helpful having access to the contents (especially metadata information) of a WRP message involved in a transaction.

Creating this ticket as a way to discuss the need and potential solutions.

During team discussions, we agreed that we can implement this in Tr1d1um anytime but that a version of it for the XMiDT stack might also be useful.
