Quotas in admin API is missing api_export_size

[Tim Simmons]

Asynchronous Zone Export:
https://github.com/openstack/designate/commit/50d1b1553e36f5927181eed65637491b14acb660

Added a quota for "api_export_size" that is the number of records allowed in an export that can be retrieved synchronously via the API.

This was not added to the admin view for quotas, and thus does not show up in the quotas for a user in the admin API:

curl localhost/admin/quotas/123
{
    "quota": {
        "recordset_records": 20,
        "zone_records": 500,
        "zone_recordsets": 500,
        "zones": 10
    }
}

The admin API docs for quotas should be updated too.
