Merged to ignite-5267 branch
> Move record serializer version from file name to file header
> ------------------------------------------------------------
>
> Key: IGNITE-5323
> URL: https://issues.apache.org/jira/browse/IGNITE-5323
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.1
> Reporter: Alexey Goncharuk
> Assignee: Alexey Goncharuk
> Labels: important
> Fix For: 2.1
>
>
> Keeping records serializer version in the WAL segment file name makes it hard
> to implement forward serializer version update because we need to rename
> files on recovery.
> Instead, we should write serializer version in the file header and use it
> when reading records.
> We should also add some boilerplate code in order to make it easier to add
> new serializer versions in the future.
