Quota-classes API extension requires tenant-to-quota-class mappings

[Eoghan Glynn]

In order for the quota-classes API extension to be functional in the absence of Turnstile, nova support for tenant-to-quota-class mappings would be required.

This could include:

 - a project_quota_class_association table in the nova DB

 - additional logic in the quota-classes API extension to establish and tear-down of such mappings

 - middleware support for setting the quota_class attribute on the request context

It took me a while to figure out why context.quota_class wasn't being set anywhere in Nova

I also don't see where it's being set in turnstile or nova_limits

Oh, wait - it's set here: https://github.com/klmitch/rs_limits

Moving to opinion status, this seems to be a long stalled effort

omg this is old, but I plan to destroy quota classes in ocata:
