Quotas command is not plugable

[Graham Hayes]

openstack quota set / show command is hardcoded to compute, volume, network quotas only.

This should be extensible to allow for client plugins to register their quota endpoints

[Dean Troyer (dtroyer)]

There does need to be a general mechanism to extend existing commands. This will also likely require changes to the plugin interface.

Also, it needs to be done safely, in the sense that the user can be confident that the assumed actions are not subverted/changed in unexpected ways.

[Graham Hayes (grahamhayes)]

I think this should be higher than "wishlist".

for example - designate is going to retire its v1 API in the near future, and we only support the openstack client plugin for the v2 API.

With no plugin point, there will be no CLI (or, incidentally UI, but that is a separate bug) for admins to set quotas or users to see theirs.
