IGNITE-9501 Exclude joined nodes from exchange latch participants.

> Exclude newly joining nodes from exchange latch

> Key: IGNITE-9501
> URL: https://issues.apache.org/jira/browse/IGNITE-9501
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.5
> Reporter: Pavel Kovalenko
> Assignee: Pavel Kovalenko
> Priority: Major
> Fix For: 2.7
>
>
> Currently, we're waiting for latch completion from newly joining nodes.
> However, such nodes don't have any updates to be synced on wait partitions
> release. Newly joining nodes may start their caches before exchange latch
> creation and this can delay exchange process.
> We should explicitly ignore such nodes and don't include them into latch
> participants.
