Moved the encrypted-AMI section from "Create Cluster" to "Running
Cluster", because it has more value there folks inspecting their
account and what has happened after the fact. Since we call out the
running instances (by count with a picture) they may wonder "where did
this unique AMI come from it is running"? It goes along with some of
the other explanations we chase with as well. The Create Cluster
section just has the whole IPI output, but no explanation of all
wizardry under the covers, calling this particular wrinkle out there
seemed a bit awkward to me.
