* Fix#6477 controller login + fix dashboard layout
- Service endpoints shoudl be on own column, cut off smaller screen
- Controller login not working due to 404 error
This is due to a breaking API change
We have requested fixes to help mitigate need for cluster name,
but for now have a default value for this
Finally, modified code so it's easier to update swagger API
and also added instructions on how to update in future
