* feat: Add comprehensive NATS and JetStream Prometheus alert rules
- Added multiple Prometheus alert rules for monitoring NATS server and JetStream metrics.
- Included alerts for:
- High connection count
- High pending bytes
- High subscriptions count
- High routes count
- High memory usage
- Slow consumers
- NATS server downtime
- High CPU usage
- High number of active connections
- High JetStream store and memory usage
- Subscription limits exceeded
- High pending messages
- Authentication timeouts
- Errors in NATS (JetStream API errors)
- JetStream consumers limit exceeded
- Exceeding max payload size
- Leaf node connection issues
- Ping operations limit exceeded
- Write deadline exceeded
- Ensured consistency between `exporter.yml` and `rules.yml` files.
- Improved overall NATS and JetStream monitoring to prevent performance degradation and ensure system reliability.
This commit enhances the visibility of NATS and JetStream operations by providing key metrics to alert on potential issues and optimize system performance.

haproxy_backend_max_sessions is the maximum number of sessions ever encountered during the lifetime of the HAProxy process. That is, it will never go down until HAProxy is restarted, so the alert continues to fire even though the situation has cleared!
This doesn't make sense. Look at the currently active sessions instead.
* Added Clickhouse
* Update rules.yml
Added reasonable time periods for each query to avoid false positives and in some cased give the system a short window to try to solve the issue.
Also changed the severity level of authentication alerts from critical to info which seems more appropriate
* Modified time period for alerts embedded-exporter.yml
I made a few adjustments in time periods.
See if they seem reasonable or not
* Replication alerts time periods were adjusted
IMHO, replication alerts must be sent right away.
This commit adds new Prometheus alert definitions to monitor indexing and query metrics in Elasticsearch clusters. These alerts are essential for detecting performance issues related to indexing and querying activities.
