> Need integrate communication with coordinator in transactions protocol:
> - reading transaction need request read ID from coordinator
> - after locks are acquired need request ID from coordinator
> - this ID should be passed to primary/backups and passed to update
> - after tx is committed need notify coordinator (note: need make sure that this notification is processed in such way so that thread executed transaction will see all his changes)
> Notes:
> - there are differences in prepare logic for optimistic/pessimistic/serializable transactions, so most probably work with coordinator should be implemented separately for these tx types
> - need support case when coordinator fails during prepare (need think is necessary rollback and retry tx or switch to next assigned coordinator)
