Logout feature

Describe the feature

Hi @prometherion
It would be nice for a already logged user with kubectl-login integrated with an oidc provider, an option to logout and invalidate oidc session.

What would the new user story look like?

As normal user, i complete a login process with kubectl-login on OIDC provider on a temporary workstation.
After complete my tasks, do a lubectl-login -r (?) o something else and invalidate session on OIDC cluster

I can take care of this, just need to understand better how to perform the OIDC session invalidation, pretty sure I need the help of @bsctl :)
