Items not found in Gemini should be reported as Warnings or Failed Events

[seth-shaw-unlv]

TL;DR: If Gemini reports back a 404 we should at least issue a warning to the user.

While testing riprap I came across an issue where the uuid for files in Drupal did not match the uuid recorded in Gemini. However, when riprap attempted to check 49 items, the status message was misleading:

Riprap checked 5 resources (5 successful events, 0 failed events) in 18.195 seconds.

I added some print lines to PluginFetchResourceListFromDrupal.php for more information which reported:

Riprap checked 7 resources (7 successful events, 0 failed events) in 17.627 seconds.

All of these 'MISSING' errors can be explained by the Gemini uuid mismatch issue, but other users may incorrectly assume that riprap checked ONLY 7 items despite their configuration being set to 50. If Gemini reports back a 404, we should at least issue a warning to the user.

Gemini is no longer a thing, so this could be closed as (I'm assuming) a 404 from Fedora would result in a warning.
