Maximum resources per VM in Buckets
Allow for specifying maximum VM resources that can be provisioned to each individual VM in a billing bucket. Ie, maximum Cores per VM, maximum RAM per VM, maximum vdisk size (per data store), maximum number of vdisks per VM, max interfaces, max IPs (per net).
The current rate card limits are great for limiting overall account limits, but give no way to define limits per VM. Maybe we don't want clients provisioning 128GB per VM, even though our HVs can do it.
