after Grizzly to Havana upgrade we noticed that the quota_usages table was
wiped out. We believe is related with bug #1245746.

Quota_usages is then updated after a user creates/delete an instance. The
problem is that quota_usages is updated per user in a tenant.

For tenants that are shared by different users this means that users that
didn't have created instances previous are able to use the full quota for
the tenant.

At the end tenants can use more resources than what is allowed by quotas.

We needed to populate quota_usages table in order to keep consistency.
