feat: namespace all Spring Profiles with 'edu.wisc.uwss' prefix

This pull request addresses issue #3 (closed), and thus begins the deprecation path for the profiles 'local-users' and 'preauth'.

There are no behavior changes with this PR, only the acceptance of the new namespaced profiles. Votes on whether we should version bump to 1.5.0? Or will 1.4.x be satisfactory?
