infra: add playbook to purge dashboard/monitoring
The dashboard/monitoring stack can be deployed via the dashboard_enabled variable. But there's nothing similar if we can to remove that part only and keep the ceph cluster up and running. The current purge playbooks remove everything. Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1786691 Signed-off-by: Dimitri Savineau <dsavinea@redhat.com> (cherry picked from commit 8e4ef7d)

| # This playbook purges the Ceph MGR Dashboard and Monitoring | ||
| # (alertmanager/prometheus/grafana/node-exporter) stack. | ||
| # It removes: packages, configuration files and ALL THE DATA | ||
| # | ||
| # Use it like this: | ||
| # ansible-playbook purge-dashboard.yml | ||
| # Prompts for confirmation to purge, defaults to no and | ||
| # doesn't purge anything. yes purges the dashboard and | ||
| # monitoring stack. | ||
| # | ||
| # ansible-playbook -e ireallymeanit=yes|no purge-dashboard.yml | ||
| # Overrides the prompt using -e option. Can be used in | ||
| # automation scripts to avoid interactive prompt. | ||
