Add a more involved multus validation test to the Rook binary. Because this is intended to be end-user runnable, make sure operator-only commands are hidden. Build this into the rook binary instead of creating a separate binary for ease, and because any binary built with the kube api becomes 40+ megabytes. We save quite a bit of space by including this in the Rook binary, which is good for keeping container layers as small as possible. Signed-off-by: Blaine Gardner <blaine.gardner@redhat.com>
