Description

Currently, partition map exchange timings printed to log(IGNITE-10493). It will be useful if we allow external tools to collect and aggregate partition map exchange metrics.

UPD: Need to implement next metrics:

• `CurrentPMEDuration` - existing metric, shows current PME duration.
• `CurrentPMECacheOperationsBlockedDuration` - new long metric. show blocking duration of PME.
• `PMEDuration` - histogram of full PME durations.
• `PMECacheOperationsBlockedDuration` - histogram of blocking PME durations.
