Integrate Docker (minimal requirements)

[php-coder]

Manual process for running production on top of the Docker containers with docker-compose.

• provide docker-compose file for running application with test profile
• provide support for running application with prod profile
• add playbook for installation and configuration of docker on a host (see https://www.digitalocean.com/community/tutorials/how-to-use-ansible-to-install-and-set-up-docker-on-ubuntu-18-04)
• modify deployment scripts to run docker container rather than a WAR file
• add documentation (copy application-prod.properties, and (optionally) database backup, run)
• run MySQL in Moscow timezone to work correctly with existing data (see All dates should be in UTC time #76)
