Do you mind attaching a screenshot too?

A little sorry, I didn't have a real cluster for testing this and attach the
scrrenshot. Now I just used unit tests for having a test.

For entries created before where the QuotaUsage of the MountTable are not set,
it returns null. This is probably OK, but then in the Web UI and the admin
tool, it shows as null. Those should consider this situation and show something
more user-friendly.

I think this problem we had met in mount table permission mode. So I want to
use a consistent way that returning a default instance (A default
RouterQuotaUsage). I have verified in admin commands but not including web UI.
Attach the updated patch, Checkstyle issue has been fixed in latest. patch.
