IGNITE-9741 SegmentAware recreated every activation

occurs before activation

> Key: IGNITE-9741
> URL: https://issues.apache.org/jira/browse/IGNITE-9741
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Maxim Muzafarov
> Assignee: Anton Kalashnikov
> Priority: Critical
> Fix For: 2.7
>
>
> The {{FileWriteAheadLogManager}} now contains:
> {{private final SegmentAware segmentAware;}}
>
> The SegmentAware have the `interrupt()` method:
> {code:java|title=SegmentAware:216}
> /**
> * Interrupt waiting on related objects.
> */
> public void interrupt() {
> segmentArchivedStorage.interrupt();
> segmentCompressStorage.interrupt();
> segmentCurrStateStorage.interrupt();
> }
> {code}
>
> Method at the {{FileWriteAheadLogManager}} de-activation sets (e.g. for SegmentArchivedStorage)
`interrupted` filed to `true` value but never revert it to `false` after activation.
> {code:java|title=SegmentArchivedStorage:114}
> /**
> * Interrupt waiting on this object.
> */
> synchronized void interrupt() {
> interrupted = true;
> notifyAll();
> }
> {code}
>
> So, the SegmentArchivedStorage after de-activation always remain interrupted.
> This can lead to undefined behaviour e.g. exchange worker hangs.
