---------------------------------------------------------------
Now all threads that request some data structure will blocked on countDownLatch
until {{DataStructuresProcessor}} will not finish initialization.
Fix merged into ignite-sprint-6.

> I suspect that {{utilityCache}} has not been initialized yet. We need to
> protect such places with latch or igniteFuture which should be released
> (completed) on the last line of "onKernalStart" and on the 1st of
> "onKernalStop" for safety.
