Vladimir Ozerov updated IGNITE-7261:
------------------------------------
Description:
Need to make sure that all statements within TX share the same MVCC version
which is assigned on first read/write.
Need to add tests for this to confirm REPEATABLE_READ behavior.
Note that regular implicit SELECTs outside transaction should only register
itself as "query" on MVCC coordinator, while SELECT inside TX must register
itself as both "query" and "tx".
