Issue when kube-aws manages/creates subnets

[davidmccormick]

Subnets in the controller stack not being referenced against the network stack when being managed by kube-aws. Map subnets back to the looked up set by name. Various additional log messages to debug level. Remove some helper functions on tempCtx types by calling the correct path in the stack templates.

Hopefully resolves #1595 which looks like it might be a long standing issue from the Netowork stack refactor.
