At the start of a partition, the order of messages may change. (#15160)

[Alek5andr-Kotov]

Changelog entry

Move changes from #15160

The partition actor puts messages in the queue until it enters the StateIdle state. Then he sends himself these messages again. There may be a situation when new messages will be processed before the accumulated ones.

#15070

Changelog category

• Bugfix

Description for reviewers

Message processing rule:

• in the StateInit state, messages are queued up in the PendingEvents queue.
• in the StateIdle state, messages are processed immediately if the queue is empty and queued otherwise.

After switching from StateInit to StateIdle, all messages in the queue are processed.
