Description

Two tests always fail on TC with the assertion

junit.framework.AssertionFailedError: Failed to wait for disconnect/reconnect event.
    at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.waitReconnectEvent(ZookeeperDiscoverySpiTest.java:4221)
    at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.reconnectClientNodes(ZookeeperDiscoverySpiTest.java:4183)
    at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.clientReconnectSessionExpire(ZookeeperDiscoverySpiTest.java:2231)
    at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.testClientReconnectSessionExpire1_1(ZookeeperDiscoverySpiTest.java:2206)

from client disconnect/reconnect events check. Obviously client doesn't generate these events as it supposed to do.
(TC runs can be found here).

It is possible to reproduce test failure locally as well, but with low probability: one failure for 50 or even 300 successful executions.
