Driver should automatically pickup contact points when Stargate is introduced to a cluster

Description

Driver should automatically pick up contact points when Stargate is introduced to a cluster. Without this automatic resolution, the client application must be restarted resulting in downtime.

Driver being used is 3.10.2.
Here are some examples of code being used to access the cluster:

session = CqlSession.builder()
  .withCloudSecureConnectBundle(Paths.get(bundle))
  .withAuthCredentials(username, password)
  .withKeyspace(keyspace)
  .build();

private CqlSession createCloudCqlSession() {
  return standardCqlSessionBuilder()
    .withCloudSecureConnectBundle(Paths.get(path)).build();
}

private com.datastax.oss.driver.api.core.CqlSessionBuilder standardCqlSessionBuilder() {
  return CqlSession.builder()
    .withKeyspace(keyspaceName)
    .addTypeCodecs(
      ExtraTypeCodecs.json(Rule.class, mapper),
      ExtraTypeCodecs.json(SegmentEntity.class, mapper),
      ExtraTypeCodecs.json(SegmentType.class, mapper),
      new EnumNameCodec<>(FilterType.class))
    .withAuthCredentials(username, password);
}

Cluster.builder
  .withClusterName(s"${system.name}-${SecureBundleConfigSessionProvider.clusterIdentifier.getAndIncrement()}")
  .withCloudSecureConnectBundle(secureConnectBundle)
  .withPoolingOptions(poolingOptions)
  .withReconnectionPolicy(new ExponentialReconnectionPolicy(1000, reconnectMaxDelay.toMillis))
  .withQueryOptions(new QueryOptions().setFetchSize(fetchSize))
  .withLoadBalancingPolicy(new TokenAwarePolicy(DCAwareRoundRobinPolicy.builder.withLocalDc(localDatacenter)
  .withUsedHostsPerRemoteDc(usedHostsPerRemoteDc)
  .build()))
