Ryan McCabe 286e0c61e4 fence_xvm/fence_virt: Add support for the validate-all status op
Add support for the validate-all status operation. In this mode,
the fence agent will validate the arguments given on either the
command line or standard input. If validation succeeds, it will
exit with code 0, otherwise it will exit with code 1.
