Description

We need to find a way to configure MVCC caches. Currently this is a global setting, which is not very convenient. Proposed solution:

1. Introduce new CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT
2. Do not allow to change cache this mode during restart (when persistence is enabled)
3. Do not allow transactions between TRANSACTIONAL and TRANSACTIONAL_SNAPSHOT caches
4. Add limitation to cache group - all caches within a group should have the same mode
