Disable Authentication & Login Page Rework (#619)

* Implemented the ability to disable authentication on a server instance. Admins will require authentication, but non-admin accounts can be setup without any password requirements.

* WIP for new login page.

* Reworked code to handle disabled auth better. First time user flow is moved into the user login component.

* Removed debug code

* Removed home component, shakeout testing is complete.

* remove a file accidently committed

* Fixed a code smell from last PR

* Code smells
