Support quotas defined on cloud provider level

[jelkosz]

A very similar issue to: #88

The ask here is that if the user has a quota defined on the cloud provider layer (for example I have an AWS account and I have my quotas defined there), I dont need to use the quotas defined on the ClusterTemplateQuota layer.
Similarly to #88, the ask is to:
1: make sure we dont stand in the way and this use case is possible
2: make sure that once the quota is violated, the appropriate error is reported to both the admin and devel personas so that the troubleshooting is easy
