Add support for labels to more K8sResource types

[MujibAzizi]

This PR adds support for labels to more classes which extend the K8sResource class.

Right now, calling setLabels on, for example, K8sService leads to the HasAttributes's __call method being used which adds the labels as a top level key rather than as a child of metadata. To correct the behaviour of this, the HasLabels must be added to all classes.

Classes to add HasLabels, tests and update documentation for:

• K8sClusterRoleBinding
• K8sConfigMap
• K8sHorizontalPodAutoscaler
• K8sIngress
• K8sNamespace
• K8sPersistentVolume
• K8sPersistentVolumeClaim
• K8sRole
• K8sRoleBinding
• K8sScale Scale is not an Kubernetes resource and thus I will not add HasLabels to it.
• K8sSecret
• K8sService
• K8sServiceAccount
• K8sStorageClass

Closes #52

Interestingly enough, I think there are more resources in this situation. 🤔

[MujibAzizi]

I will be adding it to all resources, and if that works out we can discuss to move HasLabels to K8sResource.

If you run the tests locally, does it work for you?

[MujibAzizi]

FYI: I am going to switch to using Minikube, Docker for Mac has different defaults.

For example; there is no storageclass called standard available. To fix this is not in scope of this PR.

[rennokki]

@MujibAzizi I use Minikube for testing, maybe that's what the testing is biased towards it.

If all resources accept Labels, then it can be moved to the K8sResource. However, I think it's not the same as the annotations.

[MujibAzizi]

@rennokki I've finished adding HasLabels to the required classes and added the tests. Also, I've added some generic documentation.

I'm marking the PR as Ready for Review.
