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

+## TokenRouter and other APIs:
+1. Get the API spec. This is available from a cluster at the address https://<ip>:30080/docs/swagger.json, where <ip> is the controller IP address.
+2. Copy the content from there, and add convert from OpenApi 3.0 to Swagger 2.0 so we can use the Typescript-Node client generated by https://editor.swagger.io/.
+Various converter tools are online. Alternatively, we might be able to use a different generator that has this client type (e.g. npm package @openapitools/openapi-generator-cli) but some require Java install.
+3. Copy the converted Swagger 2.0 spec into https://editor.swagger.io/
