Dan Smith c2772c2984 Gather performance data after tempest
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
