cmd/gentypes: generate request, response, event ctor (google#63)

The mapping from event request and response id to event and response types
can be done in generating. This makes sure that the maps stay up
to date with the spec.

According to the spec, RestartArguments uses a union type (oneOf) and Go does not have a union type.
Both LaunchRequestArguments and AttachRequestArguments are represented as map[string]interface{},
so we may attempt to map this to map[string]interface{}. But if the spec starts to include other
types in the union, this will be a problem. For now, use interface{}.

Added -u and -o flags, and use them with the go generate tool.
