Ceph update to a minor version


Implemented the capability to update Ceph packages to the latest minor versions on the Ceph OSD, Monitor, and RADOS Gateway nodes using the Update Ceph packages pipeline job.

Native Prometheus support

Improved Ceph monitoring by adding support for the Ceph Prometheus plugin that is based on the native Prometheus exporter introduced in Ceph Luminous. The Ceph Prometheus plugin collects a wider set of Ceph metrics as opposed to Telegraf and provides for better monitoring capabilities for large clusters. Updated Ceph-related Grafana dashboards to display new metrics.

For new deployments, the Ceph Prometheus plugin is enabled by default. For existing deployments, you can enable the Ceph Prometheus plugin manually or during the upgrade of StackLight LMA.
