Feature: Integrate Kubernetes

[werniq]

Summary:

This Pull Request introduces Kubernetes configuration files to the project, adding orchestration and management of containerized applications. The following key components have been added:

Added Kubernetes Components:

1. Namespace (0_namespace.yaml): Defines a logical space within the cluster, allowing for better resource isolation and organization.

2. Deployment (Deployment.yaml): Manages the deployment of application pods, ensuring desired replicas are running and automatically handling updates and rollbacks.

3. Service (Service.yaml): Exposes the deployed application pods, enabling network access and load balancing within the cluster.

4. Service Account (Service_Account.yaml): Provides an identity for processes running within pods, allowing access to the Kubernetes API.

5. Role (Role.yaml): Defines a set of permissions within the namespace, specifying what actions the service account can perform.

6. Role Binding (Role_Binding.yaml): Associates the defined role with the service account, granting it the appropriate permissions.

Next Possible Steps:

• Create CRD and operator for Waffle;
• Add K8S operator to extend Waffle with Firewall Rules;
• Add K8S operator to Support multiple network interfaces;

This PR contains updates from feature/graceful-shutdown;
If You wish to review, all updates are in k8s folder only.

For now I'm cool with the kubernates config, but in the future it would be nice to introduce helm as well.
