track schemes by name for error reporting
Getting an error message about a type not being in the scheme is hard to fix if you don't know which scheme is failing. This adds a name to the scheme which can be set during creation or can be set based on the calling stack. If you use the old constructor a name is generated for you based on the stack. Something like "k8s.io/client-go/dynamic/scheme.go:28" for instance.
Also moves a typer to its point of use. This was debt from previous refactors which I noticed going through.

generated code should pass go vet for go1.10
**What this PR does / why we need it**:
Update code generator and the code it generates to pass `go vet`.
go1.10 runs `go vet` whenever `go test` is run. Because of this, generated code for CRDs needs to pass `go vet`.
**Release note**:
```release-note
Code generated for CRDs now passes `go vet`.
```
