             Summary: Create cache shared preloader
                 Key: IGNITE-12069
             Project: Ignite
          Issue Type: Sub-task
            Reporter: Maxim Muzafarov
            Assignee: Pavel Pereslegin

{{CacheSharedPreloader}} must do the following:
# build the map of partitions and corresponding supplier nodes from which 
partitions will be loaded;
# switching cache data storage to {{no-op}} and back to original (HWM must be 
fixed here for the needs of historical rebalance) under the checkpoint and keep 
the partition update counter for each partition;
# run async the eviction indexes for the list of collected partitions (API must 
be provided by IGNITE-11075);
# Send a request message to each node one by one with the list of partitions to 
# Listening for the transmission handler to receive files;
# Run rebuild indexes async over the receiving partitions (API must be provided 
by IGNITE-11075);
# Run historical rebalance from LWM to HWM collected above (LWM can be read 
from received file meta page)

NOTE. Check the following things:
# Rebalancing of MVCC cache groups;
# How LWM and HWM will be set for the historical rebalance;
