Update guestbook types in Quick Start

This addresses a few issues with the guestbook types:

* Uses tabs instead of spaces
* Dedupes the `GuestbookStatus` struct
* Adds a `Guestbook` type
* Removes the `TLS` field from the `GuestbookSpec` since the
corresponding `TLSPolicy` type is neither defined nor imported
* Removes the `Nodes` field from the `GuestbookSpec` struct
