Kolla Ansible is switching to OpenSearch and is dropping support for deploying ElasticSearch. This is because the final OSS release of ElasticSearch has exceeded its end of life. Monasca is affected because it uses both Logstash and ElasticSearch. Whilst it may continue to work with OpenSearch, Logstash remains an issue. In the absence of any renewed interest in the project, we remove support for deploying it. This helps to reduce the complexity of log processing configuration in Kolla Ansible, freeing up development time. Change-Id: I6fc7842bcda18e417a3fd21c11e28979a470f1cf

Monasca - Monitoring service
Overview
Following a decline in activity within the OpenStack Monasca project, Kolla Ansible has decided to remove support for deploying it. Advice for removing it is included in the cleanup section below.
Cleanup
The cleanup command can be invoked from the Kolla Ansible CLI, for example:
kolla-ansible monasca_cleanup
This will remove Monasca service containers, and service configuration.
Following cleanup, you may also choose to remove unused container volumes. It is recommended to run this manually on each Monasca service host. Note that docker prune will indiscriminately remove all unused volumes, which may not always be what you want. If you wish to keep a subset of unused volumes, you can remove them individually.
To remove all unused volumes on a host:
docker prune
To remove a single unused volume, run for example:
docker volume rm monasca_log_transformer_data
