ignite-6096 : Fixed races on partition evict.
----
> Race between partition eviction and re-creation
> -----------------------------------------------
>
> Key: IGNITE-6096
> URL: https://issues.apache.org/jira/browse/IGNITE-6096
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Ilya Lantukh
> Assignee: Ilya Lantukh
> Fix For: 2.2
>
>
> There are a number of cases that aren't handled correctly, leading to
> assertion errors, grid hang-ups and data loss:
> - PageMemoryImpl.refreshOutdatedPage(...) - if refreshed page is currently
> scheduled for checkpoint, it will be stored if FileStore filled with zeroes.
> Reading this page later will fail.
> - GridCacheDatabaseSharedManager.restorePartitionState(...) -
> grp.offheap().onPartitionInitialCounterUpdated(...) is called under meta page
> write lock. If DataStore requires initialization, it will try to aquire write
> lock for meta page again and hang up.
> - GridDhtPartitionTopologyImpl.createPartition(...) and .localPartition0(...)
> - if partition is present but has EVICTED state, we will try to create new
> partition instance. However, DataStore for old partition might still be
> present, and we will get AssertionError when we attempt to create new
> DataStore.
