AWS image caching issues for certain accounts, when multiple accounts are defined

Issue

The stage Find image from Cluster fails to find images that that belong to certain AWS accounts on Spinnaker versions earlier than 2.23.3, when multiple accounts are defined.  

Cause

There was an issue with Spinnaker versions 2.23 and earlier where Clouddriver fails to cache images that belong to the first account (alphabetically) for each region. For example, in a region (e.g. us-east-1) with accounts named Edith, Milton, and Pixel, Edith’s images do not get cached.
