Description

Using do_node() and do_facet() sometimes requires elaborate escaping of commands lines. It is often the case that these escaped command lines behave differently when executed on local or remote nodes.

So let's add new TF functions do_node_vp() and do_facet_vp() that handle the escaping for us and work the same way on local or remote nodes.
