Support for multiple shells.

[Vad1mo]

Feature Request
if you work with multiple clusters, you often want to associate one terminal window to a cluster. With kubectx and many other tools including kubecm this is not possible. A few tools where this is possible, they use subshells, which has its set of issues.

Describe the solution you'd like
it should be possible to have multiple shells that use different Kubernetes contexts

Describe alternatives you've considered
I am currently using a combination of different tools to accomplish this.
kubens and https://github.com/danielfoehrKn/kubeswitch

Additional context

@Vad1mo Good idea, but kubecm is only used to manage kubeconfig, if you want to specify the current shell's cluster, you need to modify the current-context field in kubeconfig.

To implement this, you need multiple copies of the kubeconfig file, and then specify in kubectl to use that configuration file.

just like:

kubectl get pod --kubeconfig .kube/config

You can use alias to simplify this command above.

Edit your .zshrc( or .bashrc) file like this:

...
alias k1='kubectl --kubeconfig .kube/config1'
alias k2='kubectl --kubeconfig .kube/config2'

After that you can use different commands to operate different clusters.

k1 get pod
k2 get pod
