INFRA-172 Setup new cloud VM for PR-testing
Discussed with Tim:
- gcloud, instance type n1-standard-4 (4 CPUs, 15 GB RAM)
- Ubuntu 14.04 LTS
- 100 GB SSD for /srv, minimal / disk for easy snapshot/restore? (although we should Ansible everything so that it's easy to purge/respawn the whole VM, and no need to backup).
Tim's tasks:
- special bits to make civibuild work with DNS wildcards and Apache dynvhost.
- DNS management: create new wildcard for *.pr.civicrm.org.
