Dogfood Wikis to store self-manage performance results

We need a place to store performance results and test matrix for self-manage.

We already have some of this in wiki form. There isn't much usage of wikis at GitLab so it would be great to dogfood this with DogfoodingUse Existing Feature

Create a landing page in the quality handbook and point to wikis which stores detail test results that we can show customers.
