Shared MariaDB Backend for Create-A-Container and NGINX Port Map

[runleveldev]

Tasks:

• Insert container and port map information into a MariaDB server when created
• Add GET /containers index page for reading from the new MariaDB backend
• Add migrations to convert from the cluster current state to the new, MariaDB backed state
• Pull NGINX configuration from the Database via the HTTP API, rather than the flat file

Migration steps:

1. Pull the changes to create-a-container
2. Build a MariaDB instance and user
3. Update the create-a-container .env file with the new values
4. Restart the create-a-container service
5. Update the /var/lib/vz/snippets/register-container.sh script on intern-phxdc-pve1
6. Copy port_map.json to the create-a-container server, and run node bin/json-to-sql.js <path to port_map.json>
7. Copy the pull-config.cron to /etc/cron.d/pull-config on the NGINX server
8. Pull this repo to /opt/opensource-server on the NGINX server
9. Revert all NGINX configs back to default, then touch /etc/nginx/conf.d/reverse-proxy.conf
10. Ensure the cron job successfully reloads the NGINX configuration
