Add monitoring - Githubissues

At the moment the only insights I have into the website's performance come from

Generic stats like cpu usage and memory collected by the VPS
Loading up a page and seeing how long it takes
Manually querying pg_stat_statements
Manual examination of logs

I would like to address this by adding some monitoring service which can collect stats from uwsgi about request duration per-page, and from postgres about query statistics. Such a service should be able to break down response times by page. Candidates include Nagios, which has native uwsgi support. Other candidates include Grafana, Munin, and Zabbix.
