Make the DDF fields more similar to the current form's layout + i18n

[skateman]

Updating the initial DDF schema to look more similar to the current form's layout. Here are the catches:

• Keystone v2 as default API version - suggested by @aufi
• Events type selection changed from radio to select because DDF doesn't do inline radios
• SSL enforcement dropdown doesn't allow to select an option - reported here
• No AMQP fallback hostnames - will be added after this bug gets fixed
• Made API port for AMQP a required field
• RSA Private Key field is set to password as DDF doesn't do file uploads yet

The verify_credentials has been also updated in order to support validation for AMQP.

Looks good to me 👍

The "No AMQP fallback hostnames" doesn't seem to be an issue of OpenStack provider. The provider backend code counts with these attributes, but current UI doesn't fill it into database.

@skateman I checked out this locally I cannot see the change showed on attached screenshots. Is there any other dependent PR?

[skateman]

@aufi yeah, there's a WIP PR, you will need to rebase and run bin/update, however, it only implements validation for now, not saving.

Can we get this in please? I would like to work on this further.
