No support for kubectl plugins

[diafour]

There is a NodeGroupConfiguration example about Installing the cert-manager plugin for kubectl on master node

After applying this NGC I see the plugin is available:

# d8 k plugin list
The following compatible plugins are available:

/usr/local/bin/kubectl-cert_manager

Any attempt to use it prints d8 k help:

# d8 k cert-manager status
...
Usage:
  d8 k [flags] [options]

Use "k <command> --help" for more information about a given command.
Use "d8 k options" for a list of global command-line options (applies to all commands).

It seems any non-command argument, i.e.cert-manager is considered as wrong. It should treat such arguments as plugin names.
