> Key: IGNITE-1605

> Project: Ignite
> Issue Type: Task

> Need to provide stronger data loss check.
> Currently node can fire event - EVT_CACHE_REBALANCE_PART_DATA_LOST
> However, this is not enough since if there is strong requirement on
> application behavior on data loss e.g. further cache updates should throw
> exception - this requirement cannot currently be met even with use of cache
> interceptor.
> Suggestions:
> * Introduce CacheDataLossPolicy enum: FAIL_OPS, NOOP and put it to
> configuration
> * If node fires PART_LOST_EVT then any update to lost partition will throw
> (or will not throw) exception according to DataLossPolicy
> * ForceKeysRequest should be completed with exception (if plc == FAIL) if all
> nodes to request from are gone. So, all gets/puts/txs should fail.
