Can the plugin support start with default hosts?

[jzhoucliqr]

For eg: sudo docker-volume-netshare nfs --host 1.1.1.1:/export

This way the nfs host (IP) kinda hidden from end user, it's setup by the docker cluster admin. When launch container, end user don't need know details of the underlying nfs hosts.

This will be helpful also for different environments like dev/test/prod, the same scripts to launch services can be used in different envs.

Let me know if you guys think this is a valid use case. Thanks.
