If the generated user data bootstrap script exceeds 16kb (before being base64 encoded), AWS will reject it like this:

2018-07-31T15:15:12-04:00 [ℹ]  Parsing bootstrap script from filesystem [/Users/andy/code/kubernetes-release/_artifacts/kubicorn/1533064442/centos/master.sh]

It would be nice if Kubicorn validated the size before attempting to talk to AWS.
