> {{CacheInterceptor#onBeforePut}} can be invoked twice, and second call occurs after committing to external database (i.e. after {{CacheStoreSession#onSessionEnd}}). In case of failure in interceptor during second invocation we will get inconsistency between external database and Ignite cache.
> As you can see in attached reproducer ([^CacheStoreWithInterceptorFailureTest.patch]), second invocation happens on origination node, i.e. on transaction coordinator. 
> If transaction coordinator is primary, then fail in second invocation on primary leads to inconsistency between cache and external storage.
