Doc Text:	Sensubility has been removed from Red Hat OpenStack Platform. It was used as part of the OpsTools tooling system for interfacing with Sensu, which has been replaced by Service Telemetry Framework (STF). Since RHOSP 13 sensubility has been used as an interface to allow service health checks to be transported to STF. We have removed the sensubility interface which is not necessary for health check telemetry transport, and is now replaced with a simpler interface via collectd-exec plugin, allowing data to flow through existing telemetry transport interfaces. From an administrators perspective, the only change is to the labels exposed in the `collectd_container_health_status_bool`, with the `instance_type` label changing value from `healthy` to `base`. The metric value itself continues to be expressed as boolean with values 0 (unhealthy) or 1 (healthy).	Story Points:	---

Description Martin Magr 2022-11-10 13:24:16 UTC

Sensubility is getting deprecated in 17.1 and the only functionality it handled will be handled by collectd-exec. For this reason we need to remove collectd-sensubility from distribution and from Director deployments and it does not have any use for us.

For this to happen we will need to:
1. update tripleo-heat-templates/container_config_scripts/monitoring/collectd_check_health.py to follow collectd's plain text communication protocol
2. remove sensubility deployment logic from puppet-tripleo
3. remove sensubility related parameters and logic from tripleo-heat-templates/deployment/metrics/collectd-container-puppet.yaml, but the the logic creating podman socket as this will still be needed for collectd_check_health.py
4. remove collectd-sensubility package from distribution (eg. overcloud image)
