Zdenek Kabelac e8e4324d68 tools: enhance lvdisplay vgdisplay pvdisplay
Split description for display commands so we can better describe
it's usage and combination of individual options in man page.

Now we can separately describe:

lvdisplay, lvdisplay -c, lvdisplay -C
vgdisplay, vgdisplay -c, vgdisplay -C
pvdisplay, pvdisplay -c, pvdisplay -C

TODO: Drop validation from command code itself.
