Support quota show for current project

rtheis · rtheis · commit 27024d70af47 · 2016-04-21T11:33:24.000-05:00
The "os quota show" command "&lt;project/class&gt;" argument is now
optional. If not specified, the user's current project is used.
This allows non-admin users to show quotas for their current
project.
