Alarm examples: Replace deprecated --zookeeper option ...

with  --bootstrap-server.
Note that port number also needs to change from 2181 to 9092,
otherwise zookeeper gives strange messages
```
WARN Exception causing close of session 0x0: Unreasonable length =
308375649 (org.apache.zookeeper.server.NIOServerCnxn)
```
and clients will hang
