Added grafana dashboard and some monitoring

Added Grafana, InfluxDB, and Telegraf containers to docker-compose.development.yml. This change only adds more basic monitoring (resource usage of running docker containers) but sets us up to add more monitoring and logging.

make start-sandbox will start all of the added services, and grafana can be accessed at localhost:8090 with an admin/admin login
