Logging storage service for platform monitoring

[rcrichton]

Adds Loki with a Minio storage backend for storing service logs.

I couldn't get Loki to work in cluster mode as there appears to be a bug when running it in docker swarm. See my draft PR here for that work: #210

To test:

• Start the monitoring package
• Navigate to grafana on http://localhost:3000/
• Under dashboards in the containers folder there is a new dashbaord 'container logs'
• You may also explore the logs using Grafana's explore feature directly
• You can also view the Minio dashboard at: http://localhost:9001/

Looking good, mainly small naming convention changes.

I remembered that you need to add a condition in the CI folder in run-tests.sh, so that if we made a change in monitoring it will not run all the tests
