test_maintenance_socket with new way of running is flaky. Looks like the
driver tries to reconnect with an old maintenance socket from previous
driver and fails. This PR adds white list for connection that stabilize
the test
test_no_removed_node_event_on_ip_change was flaky on CI, while the issue
never reproduced locally. The assumption that under load we have race
condition and trying to check the logs before message is arrived. Small
for loop to retry added to avoid such situation.
