Changing the config sometimes has unintended consequences to the cloudformation stack #294
Description
As each ASG is a stack made from the combination of a macOS version, the arch, and the repo, changing any of the attributes to a new combination will result in a new stack being created and the old stack being abandoned. See this PR for example. This PR will orphan the 12.6/arm/finch-core and 12.6/x86/finch-core stacks and create a new stack with 13.2/arm/finch-core and 13.2/x86/finch-core.
The old stacks should be cleaned up somehow when renamed like this.
