Subject: [PATCH] ui: storage: LVM panel: modernize & cleanup code

using cbin, gettin rid of initComponent

this is a bit more complicated than the other refactorings in storage
recently, since we have a few fields with non trivial dependecies
between the selected mode (existing vgs/base storage) and isCreate

Because of that, using a cbind for the xtype here instead of the
pmxDisplayEditField is much more convenient
(accessing the pmxDisplayEditField and the editField below is currently
not really ideal)
