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

# 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.
