Update pool conversion function to handle also conversion of thick LV to thin LV by moving thick LV into thin pool data LV and creating fully provissioned thin LV on top of this volume. Reworking existing conversion to use insert_layer_for_lv co the uuid is now kept with thin-pool - this should however not really matter as we are doing full deactivation & activation cycle. With conversion to thin LV user can use same set of arguments to set chunk-size. TODO: add some smart code to decide best values for chunks sizes.
