Description

After task StartCachesInParallel we can start caches in parallel but GridQueryProcessor is narrow place because it should be start consistently by following reasons:

• checking index to duplicate(and other checking) require one order on every nodes.
• onCacheStart and createSchema contains a lot of mutex.
• maybe it has other reasons.

After this task GridCacheProcessor#prepareStartCaches should be rewrited.
