Proposal:
- create sretools.wikimedia.org in DNS
- Puppetize microsite / httpd::site for this site, run on role::miscweb
- puppetize the filter_victorops_calendar script + cron job, running under a sysuser on miscweb, serving from a URL like sretools.wikimedia.org/oncallcalendar.ics
- puppetize sremap, serving from a URL like sretools.wikimedia.org/sremap/ (protected by CAS)
