[libvirt] [PATCH 2/3] Doc: Improve the document for nodesuspend



Explicitly lists the possible values for "--target" option;
Gets rid of the confused strings like "Suspend-to-RAM";
Emphasises the node *has to* be suspended in the time duration
specified by "--duration". And rewords the entire document a
bit according to the API's implementation and document.
