Avoid race condition when polling for topology

[npepinpe]

Description

This PR fixes a potential race condition when starting the EmbeddedBrokerRule. We poll for the topology and wait until it's complete. Unfortunately, if we're too fast and the request is rejected, the .join() will throw, which will be rethrown by Awaitility (as when using untilAsserted it only catches AssertionError), failing the test. By ignoring exceptions here we can focus on just failing when the topology is never complete (Awaitility will print out the last failure in that case).
