Limit resources per VM

[kvaps]

Description
Hi it would be nice to make an opportunity to limit the highest plank of CPU, vCPU, RAM and Disk Space created for each VM.

Use case
Users might be confused by creating the VM larger than hosts capable to handle it. Customer will see the VM stuck on PENDING state.

Interface Changes
Additional quotas for user and groups:

#  VM = [
#    INSTANCE_MEMORY           = <Max. allocated memory (MB) for one VM>
#    INSTANCE_CPU              = <Max. allocated CPU for one VM>
#    INSTANCE_VCPU             = <Max. allocated VCPU for one VM>
#    INSTANCE_SYSTEM_DISK_SIZE = <Max. allocated system disk (MB) for one VM>
#  ]
