Delete multiple cluster from your config using selection

[narwhal99]

Is your feature request related to a problem? Please describe.
You have to -> kubecm delete -> select a cluster -> Enter Yes, to delete a cluster from your config.
And do it over for every cluster you want to delete.
Using oc login theres a lot of entries in my kubeconfig

Describe the solution you'd like
It would be way faster and easier to select an item for example with a space you want to delete.

You can delete multiple contexts non-interactively, as in the following example:

kubecm delete my-context1 my-context2

Of course, if you want to delete multiple contexts interactively, I'd be more than happy for you to describe this feature in more detail or feel free to open up a PR to implement so.
