Replace angular-based infra provider forms with the DDF component

[skateman]

Replacing the infra provider forms with the DDF implementation, the following schemas have been converted:

• VMware - Adjusted DDF schema for infra provider creation + validation manageiq-providers-vmware#598
• OpenStack - Split up the common DDF for infra and cloud manageiq-providers-openstack#611
• SCVMM - Adjusted DDF schema for provider creation + validation manageiq-providers-scvmm#160
• RHEV - Adjusted DDF schema and validation for creating new providers manageiq-providers-ovirt#509

The form is still in a dual mode, so it's easy to compare the old forms with the new ones...

Parent issue: ManageIQ/manageiq#18818

@skateman Noticed 2 differences from old version of the form in flash messages.

• Flash message is missing when pressing Reset button on edit Provider form, need to open a separate issue to make it consistent among all DDF forms.
• When pressing Cancel button on edit form, record name/display name is missing from the flash message
