URL: https://github.com/apache/cloudstack/pull/13226
### Description
PR #12975 introduced support for live scaling VMs with fixed service
offerings on KVM. However, it did not remove a constraint in the Kubernetes
cluster scaling workflow that prevented changing cluster compute offerings
while the clusters were running.
This PR removes this leftover constraint, enabling dynamic scaling of
Kubernetes cluster offerings.

### How Has This Been Tested?
- Created a k8s cluster with a compute offering of 2 vCPUs and 4096 MiB of
memory (without CPU cap):

- Scaled the k8s cluster and upgraded its offering to 2 vCPUs and 4096 MiB
of memory (with CPU cap):
