Allow bi-directional management of services

Follow-up on https://github.com/portainer/k2d/issues/79

Assuming bi-directional management is interesting for our users, we should potentially add bi-directional service management.

This would allow support for the following operations:

• List services - kubectl get svc -A, kubectl get svc
  • Listing services across all namespaces or the default namespace will include a service for each container created via docker run... that expose at least one port. These will default to hostPort type services.
• Inspect a service - kubectl get svc/container-name, kubectl describe svc/container-name
  • Allows you to inspect a service associated to a container created via docker run...
• Delete a service - kubectl delete svc/container-name
  • Allows a user to remove any port exposed on a container created via docker run...
