cassandra: Refactor the former installation scripts
- Move the previous yaml base configuration to a puppet template
- Install cassandra via the archive instead of the debian packages It gives more flexibilities regarding the multi instances configuration
- Support multi instance per server
- Centralize the configuration to the cassandra.yaml file
There is still some work to do:
- Manage more cassandra configuration properties
- Add the tcp port monitoring
- Wire the exporter metrics to one of the prometheus
