[openstack-dev] [horizon] [ux] Changing how the modals are closed in Horizon

Hi Aaron,

The only way to combine 2 aforementioned solutions I've been thinking of is
to implement David's solution as the 4th option (in addition to
true|false|static) on a per-form basis, leaving the possibility to change
the default value in configs. I guess this sort of combining would be as
simple as just putting both patches together (perhaps, changing a bit
David's js-code for catching 'click' event - to work only for the modal
forms with [data-modal-backdrop='confirm']).
