### Description
When scaling the compute offering of stopped k8s clusters, the following
exception is thrown in the Management Server logs:
```bash

It is relevant to highlight that, although the exception is thrown, it does
not interfere in the scaling process.
This PR proposes to fix the exception throw by adding a new state and
transitions to the Kubernetes Cluster finite state machine.

### How Has This Been Tested?
Before upgrading the environment with the current PR's changes, I verified
that when scaling the compute offering of stopped k8s clusters, the exception
was thrown.
After applying the PR's changes, I verified that when scaling the compute
offering of stopped k8s clusters, no exceptions were thrown.
