Add configure option --with-device-nodes-on

Add configure option --with-device-nodes-on

Make configurable default behaviour how to deal with device node creates.
With udev system natural options should be  'resume'.
For older systems where user expect there is node in /dev/mapper immediately
after  dmsetup create --notable  -  use 'create'

FIXME:
Code needs fixing passing this flag through udev cookie.
