Output external CAs in swarm mode with docker info

Browse source 
This fix tries to address the issue raised in 25195 where external
CA configurations are not present in `docker info`.

This fix adds the output of external CAs in `docker info` in swarm
mode.

The test is done manually with:
```
docker run -p 8888:8888 -e CXFSSL_ADDRESS=0.0.0.0 -d fabric8/cfssl
docker swarm init --external-ca protocol=cfssl,url=http://172.17.0.2:8888
```

The `docker info` output:
```
 Managers: 1
 Nodes: 1
 Orchestration:
  Task History Retention Limit: 5
 Raft:
  Snapshot interval: 10000
  Heartbeat tick: 1
  Election tick: 3
 Dispatcher:
  Heartbeat period: 5 seconds
 CA configuration:
  Expiry duration: 3 months
  External CAs:
    cfssl: https://172.17.0.2:8888
```

This fix fixes 25195.
