Ivan Rakov updated IGNITE-5971:
-------------------------------
    Description: 
Bunch of tests inherited from CacheContinuousQueryFailoverAbstractSelfTest have 
flaky #testMultiThreadedFailover test. It fails from time to time in all 
inherited test classes.
CacheContinuousQueryAsyncFailoverAtomicSelfTest.testFailoverStartStopBackup 
fails with problem that looks the same.
