Looks like memleak in case of error. goroutine knows nothing about return (no channel readers) and will try to call collectors[i].Describe(ch)

What you think about having a couple of unit tests in metrics package that print list of metrics for IR and Storage into stdout instead of having a separate application? These tests can be ignored with build tag.

I like the idea, but I've thought we need to integrate it into some pipeline.
Probably some go:generate is enough, though.
