Sorry, this is a two part PR:
1. We're now retrying every flaps call where it seems relevant. I
noticed in tracing that some builder creations were failing
unnecessarily
2. We're now catching more errors. For whatever reason, flaps can return
"App not found" or "Could not find app" when it has an issue finding an
app. We're doing string comparisons :vomit: to find both

I realize that I'm not correctliy recording the status codes in the way
that I wanted. We're now always recording flaps error status codes
