> 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.
