Hello!
I got some issue. Aslo I tried add **heartbeats** topic in `topics.exclude`
and `topics.blacklist` but it isn't help.
I have two geo cluster. And need use A as backup for B and vice versa.
Replication topics from DC A to DC B with prefix `dc-a-`
mm2 in DC B:
```ini
# sync kafka topics dc-a -> dc-b
clusters=dc-a, dc-b-target
# replicated topics -
replication.policy.separator=-
dc-a.bootstrap.servers=dc-a:9092
dc-b-target.bootstrap.servers=dc-b:9092
dc-a->dc-b-target.enabled=true
topics.blacklist=heartbeats, dc-b-.*
topics.exclude=heartbeats, dc-b-.*
```
Replication topics from DC B to DC A with prefix `dc-b-`
mm2 in DC A:
```ini
# sync kafka topics dc-b -> dc-a
clusters=dc-b, dc-a-target
# replicated topics -
replication.policy.separator=-
dc-b.bootstrap.servers=dc-b:9092
dc-a-target.bootstrap.servers=dc-a:9092
dc-b->dc-a-target.enabled=true
topics.blacklist=heartbeats, dc-a-.*
topics.exclude=heartbeats, dc-a-.*
```
For success story i want see topics in DC A:
```bash
first # local topic in DC A
dc-b-first # topic from DC B
```
topics in DC B:
```bash
first # local topic in DC A
dc-a-first # topic from DC A
```
For example result in dc-b (aslo looks like bug -- exclude does not work for
**heartbeats** via `topics.exclude=dc-b-.*`):
```
root@dc-b:~# /opt/kafka/bin/kafka-topics.sh --bootstrap-server
localhost:9092 --list | grep heartbeats
dc-a-dc-b-dc-a-dc-b-dc-a-dc-b-dc-a-dc-b-dc-a-dc-b-dc-a-dc-b-dc-a-dc-b-heartbeats

dc-a-dc-b-dc-a-heartbeats
dc-a-dc-b-heartbeats # <- this should not replicated via
`topics.exclude=dc-b-.*`
dc-a-heartbeats
heartbeats
