Usage ping for GitLab CI/CD Pipelines

We have a usage ping for ci_pipelines, but I'm unsure if that's all pipelines, including external services. We need a usage ping of GitLab CI/CD Pipelines.

@zj Would you be willing to help with that?

@markpundsack Right now its just a Ci::Pipeline.count query, just for reference. I think you already have what you're looking for, but I'll double check.

@zj That's still pretty ambiguous to me. I assume, but don't know for sure, that Ci::Pipeline.count includes external services like Codeship or other things that send CI statuses. Is that correct? If so, then we need something else to track just pipelines with GitLab CI (i.e. from .gitlab-ci.yml).

@markpundsack Well, it seems to me that pipelines are created in the Ci::CreatePipeline service, while the rest is create through hooks, so you got what you want already.

@markpundsack I stand corrected, Ill create a MR for this.
