Description

It's useful for a user to get it's quota restriction.

The following proposal will be implemented to allow users to retrieve their quota usage and limits.

quotas (String[Quotas]) map of quota root (identifier of a quota for this mailbox) to Quotas.
Quotas are a map of quota type ('STORAGE' for size quota, 'MESSAGE' for count of messages quota) to Quota object. A quota object contains 2 fields, used and max.
  used (Number) number of messages, or size in bytes for storage
  max (Number|null) maximum number of messages, or maximum size in bytes for storage. Null means unlimited

Example:

...
quotas: { 
     '#private&user': {
         'STORAGE': { 'used': 10, 'max': 512 },
         'MESSAGE': { 'used': 42, 'max': null }
     }
}, ...
