tasks
                 Key: IGNITE-29107
                 URL: https://issues.apache.org/jira/browse/IGNITE-29107
             Project: Ignite
          Issue Type: Task
            Reporter: Ilya Shishkov
            Assignee: Ilya Shishkov
             Fix For: 2.19


h2. Description

Currently there is no way to determine whether a data region is persistent or 
in-memory from its metrics. 
We can add a boolean metric {{PersistenceEnabled}} to each data region, which 
will return {{true}} for persistent regions and {{false}} for in-memory 
regions, determined once at startup. 

h2. Acceptance Criteria
 * Every data region exposes the {{PersistenceEnabled}} metric after node 
startup.
 * Value is {{true}} for persistent regions and {{false}} for in-memory regions.
 * Value always matches the region's persistence configuration (except for 
client nodes).
 * Metric is visible in standard monitoring (e.g., JMX) alongside other data 
region metrics.
 * Existing data region metrics behave unchanged.
