Feature: Merge Kuber and Kube-eleven

[Despire]

Description

Kube-eleven: This service is responsible for building and destroying Kubernetes clusters.
Kuber: This service performs actions immediately after a Kubernetes cluster has been built, such as patching nodes, deploying longhorn, deleting nodes.

Both of these services directly work on the k8s cluster, These two services are correlated as without a successful pass during the kube-eleven stage, kuber cannot continue. I suggest we merge these two together into a single service.

By merging these two services, we can:

• maintain one less service overall
• refactor the code and make it more robust
• aiming to reduce complexity.

The end result would be to have 5 micro-services in total:

Manager: takes care of scheduling of what tasks are supposed to be done to achieve the desired state.
Builder: completes task from the manager.
Terraformer: builds the infra.
Ansibler: connects the infra.
Kuber+Kube-eleven: Uses the infra to create a working k8s cluster.

Exit criteria

• Successful integration of Kube-eleven and Kuber.
• Testing completed for merged functionality.
• Documentation updated to reflect changes.
