> Issue Type: Task
> Reporter: Anton Vinogradov

> The main idea is to provide special "read from cache" mode which will read a value from primary and all backups and will check that values are the same.
> In case values differ they should be fixed according to the appropriate strategy.
> ToDo list:
> 1) {{cache.withReadRepair().get(key)}} should guarantee values will be checked across the topology and fixed if necessary.
> 2) LWW (Last Write Wins) strategy should be used for validation.
> 3) Since LWW and any other strategy do not guarantee that the correct value will be chosen.
> We have to record the event contains all values and the chosen one.
