IGNITE-8122 Restore partition state to OWNING if unable to read from page
memory.

> Partition state restored from WAL may be lost if no checkpoints are done

> Key: IGNITE-8122
> URL: https://issues.apache.org/jira/browse/IGNITE-8122
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.4
> Reporter: Pavel Kovalenko
> Assignee: Pavel Kovalenko
> Priority: Minor
> Fix For: 2.5
>
>
> Problem:
> 1) Start several nodes with enabled persistence.
> 2) Make sure that all partitions for 'ignite-sys-cache' have status OWN on
> all nodes and appropriate PartitionMetaStateRecord record is logged to WAL
> 3) Stop all nodes and start again, activate cluster. Checkpoint for
> 'ignite-sys-cache' is empty, because there were no data in cache.
> 4) State for all partitions will be restored to OWN
> (GridCacheDatabaseSharedManager#restoreState) from WAL, but not recorded to
> page memory, because there were no checkpoints and data in cache. Store
> manager doesn't have any allocated pages (including meta) for such partitions.
> 5) On exchange done we're trying to restore states of partitions
> (initPartitionsWhenAffinityReady) on all nodes. Because page memory is empty,
> states of all partitions will be restored to MOVING by default.
> 6) All nodes start to rebalance partitions from each other and this process
> become unpredictable because we're trying to rebalance from MOVING partitions.
