[Feature Request] Implement plugin for cluster-stacks

[tonifinger]

Based on #710, a plugin must be added that creates k8s clusters with the usage of cluster-stacks

To do this, we need to derive a plugin from Tests/kaas/plugin/interface.py that implements the following two methods:

• _create_cluster
• _delete_cluster

The current plugin implementation from kind can be used as an example: Tests/kaas/plugin/plugin_kind.py

Summary of Work Done on Issue #774 (In Progress):

• Investigation: Reviewed requirements and related issue #710 to understand the necessary steps for implementation.
• Plugin Implementation: Developed the cluster-stacks plugin by deriving it from Tests/kaas/plugin/interface.py, implementing the _create_cluster and _delete_cluster methods, and pushed the initial commit to a branch.
• Cluster Deployment: Deployed a Kubernetes cluster using the cluster-stacks plugin and verified the functionality.
• Cluster Deletion: Successfully deleted the created cluster-stack cluster.
• Testing: Conducted tests to validate the creation and deletion of the Kubernetes cluster using the cluster-stacks plugin on the GX-SCS infrastructure.
• Code Refactoring: Refactored the code by replacing simple sleep statements with wait definitions for CSO and CAPI pods to improve reliability.
• Adaptation: Made necessary adaptations to the cluster-stacks plugin based on changes in the branch 710-feature-request-enable-compliance-tests-to-use-plugins-for-cluster-provisioning.
• Draft PR: Created a draft pull request to initiate the review process for the implemented plugin.
