Monitoring improvements

This release features multiple improvements to monitoring your clusters:

• Attached GridGain 8 clusters now have alerting enabled by default. The ignite.longJVMPausesCountChange metric is monitored for never being over 0 milliseconds.

• Cluster health widget now tracks if some nodes in the GridGain 8 cluster are offline, and provides the ID of nodes that are offline. ignite.longJVMPausesCountChange

• You can now manage what data is collected from GridGain 9 or Apache Ignite 3 clusters from Control Center interface without updating your cluster configuration.
