Question about Atmos Storage Quotas

Hello,

I'm new to Atmos but we have installed the latest version (2.1).  I'm trying to figure out 2 things:

1) How storage quotas work and are set

2) How to manage storage quotas via the Atmos Management API

There is some detail on storage quotas in the Admin guide starting at pg109 but it's not clear about how they are set nor the purpose of them as they don't appear to automatically limit a subtenants usage.  Based on what the admin guide states I need to deploy text files that limit a subtenant's write access once their quota has been exceeded - I guess I don't understand why write limitations wouldn't kick in automatically if a storage quota is set.

Finally, there's nothing in the Management API guide about how to set quotas via the REST mgmt API.  Any insight into this feature is much appreciated, thanks!
