Decommision the blogs domain workaround once the blogs.ft.com domain is decommissioned

[JakeChampion]

What

We have a workaround to make old blog images work: https://github.com/Financial-Times/origami-image-service/pull/641/

When requests to those old blog images no longer occur, let's remove this workaround.

Details

When the splunk search returns less than 100 results (ideally 0) we should delete the code which makes the old blog images work. We already have an alert setup in Splunk to email us when the request count drops below 100 for these images.

Here is the splunk search we use:

index=restricted_ftdotcom source=133g5bgac00hv4v8t0dmry request.path="/__origami/service/image/v2/images/*" request.path="*blogs.r.ftdata.co.uk*" request.referrer="http*" | table request.referrer | sort request.referrer | uniq request.referrer

Splunk alert -- Likely only Jake can see this.
