This makes us gather a bunch of consistent statistics after we run tempest that can be use to measure the impact of a given change. These are stable metrics such as "number of DB queries made" and "how much memory is each service using after a tempest run." Note that this will always run after devstack to generate the JSON file, but there are two things that control its completeness: - MYSQL_GATHER_PERFORMANCE must be enabled to get per-db stats - Unless tls-proxy is enabled, we will only get API stats for keystone Change-Id: Ie3b1504256dc1c9c6b59634e86fa98494bcb07b1
