There used to be three definitions of a Component type, and conversion
routines between the three. Since the use case is always the same, and
the Component semantics are defined by versions.go and the installer, it
seems appropriate to define the Component type there and import it in
the necessary places.

* Use common cryptsetup backend in bootstrapper
* Use common cryptsetup backend in disk-mapper
* Use common cryptsetup backend in csi lib
