There's definitely two implementations and their access is confusing:

The second button opens a modal, I am suspecting it is defined in a provider repo and it's already talking to the API so I guess here we will definitely need to specify which provider can do what field. cc @agrare

@skateman looks like OpenStack and NSX-t have create_security_group implemented, the provider modal is probably coming from NSX-t
