Provider does not allow dynamic scaling #273
Description
Hello there,
it seems like the provider does not allow dynamic scaling of instances.
Currently the provider calls updateVirtualMachine everytime something has changed on a cloudstack_instance resource. This updates the compute instance in CloudStack Management but does not change the actual VM.
To actually change the VM scaleVirtualMachine must be called.
The provider should check if details.cpuNumber, details.cpuSpeed or details.memory has changed and call scaleVirtualMachine prior to updateVirtualMachine or skip updateVirtualMachine at all when nothing else changed.
Thank you for looking into this.
