Drupal 8 port of the No Current Password drupal 7 contrib module.
Ported by David Czinege 2016-07-22
This module disables the "current password" field that has been added to Drupal 8's user edit form, at user/%/edit.
When you enable this module, the current password field will be removed by default. To enable the password field again, go to admin/config/people/accounts and uncheck the "Do no require current password" checkbox.
