Description

As of now we have query statistics (org.apache.ignite.IgniteCache#queryMetrics) , but have few issues.
1) Duration execution it just time between start execution and return cursor to client and doesn't include all life time of query.
2) It doesn't know about multistatement queries. Such queries participate in statistics as single query without splitting.
3) API to access the statistics expose as depend on cache, however query don't have such dependency.
 
Need to create parallel similar realization as we already have.
Use new infrastructure of tracking running queries developed under IGNITE-10621 and update statistics on unregister phase.
Expose API on upper level then it placed now. Right place will be written later.
