Add scaffolding for gitlab:performance:check
In support, we are working on tooling to help us gather data to diagnose performance problems in customer installations. There is a lot of brainstorming and prototyping going on in this area right now:
gitlab-com/support/support-team-meta#1492 (closed) https://gitlab.com/andrewn/support-tool https://gitlab.com/gitlab-com/support/toolbox/gitlabsos https://gitlab.com/gitlab-org/gitlab-ce/issues/58048
Eventually we want to ship this with the product, so the purpose of this issue is to start that process by adding scaffolding in the SystemCheck rake task infrastructure so we can start adding pieces.
The idea is to create something similar to gitlab:check that applies the knowledge we've learned while debugging customer performance problems in order to do a standard set of analyses on the system to speed up the resolution when customers have issues.
To satisfy this issue, we will just have the basic infrastructure in place so we can start adding pieces to it.
