Subject: [PATCH] Update cloudformation-template-ipsec

- Add "CreationPolicy" to notify the user when the setup script succeeds on the virtual machine. The stack fails if the script fails.
- The timeout is 10 minutes.
- This feature is to be tested on Debian(s). I have personally tested it on Ubuntu20.
