Description

org.apache.hadoop.hdds.GenericCli is the based class for all the Ozone related command line application. It supports to define custom configuration variables (D or --set) but doesn't support the '-conf ozone-site.xml' argument to load an external xml file to the configuration.

Configuration and OzoneConfiguration classes load the ozone-site.xml from the classpath. But it makes very hard to start Ozone components in IDE as we can't modify the classpath easily.

One option here is to support the --conf everywhere to make it possible to start ozone cluster in the IDE.

Note: It's a nice to have for 0.4.0. I marked it as 0.5.0 but safe to commit at anytime to 0.4.0
