Persist the stack name only
Issue #3
new
provision-aws
can persist just the stack name (plus keypair name). The stack resources can be skipped.
This allows the clients to:
* run cleanup-aws
for some old, abandoned stacks, by just providing the stack name in the stack.json
* run execute-aws
or cleanup-aws
even if provision-aws
gets interrupted or fails for another reason, because we can dump stack.json
before provisioning
