Description

Steps to reproduce:

1. Start sample docker cluster
2. Run ozone admin om getserviceroles with unknown service ID

repro

$ cd hadoop-ozone/dist/target/ozone-*/compose/ozone
$ docker-compose up -d
$ docker-compose exec scm bash
bash-4.2$ ozone admin om getserviceroles --service-id=om
Error: This command works only on OzoneManager HA cluster. Service ID specified does not match with ozone.om.service.ids defined in the configuration. Configured ozone.om.service.ids are[]bash-4.2$

• The message should include a space before [], and a newline at the end (prompt should appear in next line).
• Wording of the message could also be improved.
