> We need to find a way to configure MVCC caches. Currently this is a global setting, which
is not very convenient. Proposed solution:
>  # Introduce new {{CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT}}
>  # Do not allow to change cache this mode during restart (when persistence is enabled)
>  # Do not allow transactions between {{TRANSACTIONAL}} and {{TRANSACTIONAL_SNAPSHOT}} caches
>  # Add limitation to cache group - all caches within a group should have the same mode
