[rust-server] (Re-)Adding support for rust-server (#290)

* First attempt at getting rust-server working

* Solve the problem of spurious 'object's

* We've found the missing models

* Catch some single-var objects correctly

* Get single-param models 'working'

* Got files working

* Remove surplus logging

* Disable some things to get it compiling

* `cargo test` now passes as well

* Create rust-server-specific petstore.yaml

We've commented out a few bits that rust-server doesn't yet support

* Remove commented-out code

And finally get rid of the generation date in the sample
