Add new `talosctl install` command using the LifecycleService.Install
streaming API with support for insecure (maintenance) mode and progress
reporting. Refactor `talosctl upgrade` to use the new
LifecycleService.Upgrade streaming API with automatic fallback to the
legacy MachineService.Upgrade path for older Talos versions.
