feat: support bi-directional container management

[deviantony]

Closes #79

This PR implements bi-directional management for containers.

It adds support for externally created containers when using the following operations:

• List pods - kubectl get pods -A, kubectl get pods
  • Listing pods across all namespaces or the default namespace will include the containers created via docker run... as well as pods created via k2d
• Inspect a pod - kubectl describe pods/container-name, kubectl get pods/container-name
  • Allows you to inspect a pod associated to a container created via docker run...
• Get the logs of a pod - kubectl logs pods/container-name
  • Allows you to get the logs of a pod associated to a container created via docker run...
• Delete a pod - kubectl delete pods/container-name
  • Allows you to delete a pod associated to a container created via docker run...
