API for deleting saved impressions #295
Description
In #289, we added a crude mechanism for deleting saved impressions from the impression site side. In discussion, the possibility that we add a mechanism for deleting impressions in a more targeted fashion. For instance, if things were broken last Tuesday, an API to remove impressions saved last Tuesday might be good.
ARA experience shows that maybe we don't need to do anything. But knowledge about these things is an asset.
