Flaky tests

[gawarz]

There are some flaky tests:

should be resilient to transient unavailability of EC in one DC() - pl.allegro.tech.servicemesh.envoycontrol.reliability.EnvoyControlDownInOneDc

failed build

latency between service registration in local dc and being able to access it via envoy should be less than 0,5s + stateSampleDuration() - pl.allegro.tech.servicemesh.envoycontrol.EnvoyControlSynchronizationRunnerTest

failed build
