Review comment:
I recommend using GeodeAwaitility instead of a while-loop without
timeout (I realize that ConcurrencyRule is ultimately providing the
cancellation):
```
await()
.ignoreException(ClusterManagementException.class)
.until(() -> client.get(server0) != null);
```

Review comment:
I recommend annotating with `@VisibleForTesting` because the method
would probably be private if we didn't need to call it directly for testing.

Review comment:
ExecutorServiceRule would really clean this up and I think we should
look into merging these two rules. In general, I think ExecutorServiceRule is
preferable (I can explain outside of PR). If you switch to ExecutorServiceRule
the test could use an assertion in await and seems much more readable to me:
```
import static java.util.concurrent.TimeUnit.MILLISECONDS;
import static org.apache.geode.test.awaitility.GeodeAwaitility.await;
import static org.assertj.core.api.Assertions.assertThat;
@Rule
public ExecutorServiceRule executorServiceRule = new ExecutorServiceRule();
@Test
public void getStartingMember() throws Exception {
Member server0 = new Member();
server0.setId("server-0");
Future<Void> startServer = executorServiceRule.submit(() -> {
cluster.startServerVM(0, webContext.getLocator().getPort());
});
await()
.ignoreException(ClusterManagementException.class)
.untilAsserted(() -> assertThat(client.get(server0)).isNotNull());
startServer.get(getTimeout().toMillis(), MILLISECONDS);
}
```

> Exceptions in locator logs when hitting members REST endpoint
> -------------------------------------------------------------
>
> Key: GEODE-8078
> URL: https://issues.apache.org/jira/browse/GEODE-8078
> Project: Geode
> Issue Type: Bug
> Components: management
> Reporter: Aaron Lindsey
> Priority: Major
> Labels: GeodeOperationAPI
>
> I'm seeing the following exceptions in locator logs when I try to hit the
> REST endpoint /management/v1/members/\{id} before the member has finished
> starting up. The reason I need to do this is because I have a program that is
> polling that endpoint to wait until the member is online. Ideally these
> errors would not show up in logs, but instead be reflected in the status code
> of the REST response.
