Improve the cmd: get clusters

[cmoulliard]

• Improve the cmd: get clusters to show the cluster, nodes and their internal IP.
• Created a help function to access globally to the kube client.
• Add a new parameter to set the kubeconfig path

  
  ./idpbuilder -h
  Manage reference IDPs

Usage: idpbuilder [command]

Available Commands: completion Generate the autocompletion script for the specified shell create (Re)Create an IDP cluster delete Delete an IDP cluster get get information from the cluster help Help about any command version Print idpbuilder version and environment info

Flags: --color Enable colored log messages. -h, --help help for idpbuilder --kubePath string kube config file Path.

- Command currently shows:

Cluster: my-konflux URL of the kube API server: https://127.0.0.1:63473 TLS Verify: false Node: my-konflux-control-plane Internal IP: 10.89.0.2

- #445

If several clusters/contexts/nodes have been created, then the command will output the following information:

Cluster: dabou
URL of the kube API server: https://127.0.0.1:53369
TLS Verify: false
External Port: 9443

Node: dabou-control-plane
Internal IP: 10.89.0.4
Capacity of the node: 
  cpu                  8
  memory               12.66 GB
  pods                 110

I refactored the code to show the clusters using a Table
