Here we should think about - whether there should be one
generic  '_params'  object with subsection (?unions?)
for various operations - since there is a lot of common
options between  lvcreate/lvconvert/lvresize....

lvm2api then might create access(set/get) methods to prepare this object
and pass this handle into more generic function.
