## What changes were proposed in this pull request?
Currently if we run
```
./sbin/start-master.sh -h
```
We get
```
Usage: ./sbin/start-master.sh [options]
18/10/11 23:38:30 INFO Master: Started daemon with process name: 33907C02TL2JZGTF1
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for TERM
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for HUP
18/10/11 23:38:30 INFO SignalUtils: Registered signal handler for INT
Options:
-i HOST, --ip HOST Hostname to listen on (deprecated, please use --host or -h)
-h HOST, --host HOST Hostname to listen on
-p PORT, --port PORT Port to listen on (default: 7077)
--webui-port PORT Port for web UI (default: 8080)
--properties-file FILE Path to a custom Spark properties file.
Default is conf/spark-defaults.conf.
```
We can filter out some useless output.
