yeah, I'd originally tried query.proto but protoc complains about filenames shadowing one another with the existing query.proto, which is why I chose service.proto but agree it could be better named.

I've gone with metricsquery.proto. Let me know if you prefer another name.

perhaps we should move the gen-types under api_v2/metrics?
