> {{java.lang.OutOfMemoryError}} should be handled accordingly to provided failure handle. 
> There are at least 3 types of places where OOM can be catched:
> 1. Crtitical workers that listed in IEP-14. In this case we just handle failures as {{CRITICAL _WORKER_TERMINATED}}.
> 2. Other threads. We should consider uncaught or default exception handlers for such treads.
> 3. {{IgniteUtils.convertException()}} and {{IgniteUtils.convertExceptionNoWrap}} methods that should invoke failure handler in case of {{OutOfMemoryError}}.
> Some memory should be reserved at node start to increase chances of OOM handling.
