Support AD in cluster connection dialog (#7367)

- Use token API to get auth token before using other endpoints. Note this needs server updates before it'll work as expected (will only checkin after verifying this)
- Add auth option in controller UI and plumb through connection save, load, and uses of the controller API
Because the swagger spec is split in 2 created new file for the 2nd swagger spec including token auth endpoints. These come from a running cluster and instructions were updated to reflect this.

New UI Changes:
- Added authentication type field with "Basic" and "Windows Authentication" as the options
- Moved error notifications to the dialog instead of separate notification window. That's the recommended pattern
- Username / password aren't required for Windows Authentication. I couldn't find a way to change required status in form container on switching from Windows => Basic Auth so have error show on clicking OK. 
- Controller URL should use ":" not "," for IP:Port
