Description

Follow the same pattern as the Loki and Alloy roles we currently have:

In our distro_grafana role, add a pin for Prometheus version 2.*
Add an arvados_promtheus role that depends on distro_grafana. It:
- Installs the prometheus package
- Installs the configured arvados_prometheus_config_file to the right place
- Enables and re/starts the service
Add a play to install-arvados-cluster.yml so hosts in the arvados_prometheus group run the arvados_prometheus role.
