Propagate 1.6.x down through the sub-modules.

New optional user interface for populating the LocalUserDetailsManagerImpl instance provided in the 'local-users' profile. The default configuration will still use the existing LocalUserDetailsAttributesMapper.Default implementation.

To switch to the new loader, set the 'edu.wisc.uwss.local.userDetailsLoader.enabled' Environment property to true. The default resource loaded is edu/wisc/uwss/local/local-users.json (classpath), to change that location set the 'edu.wisc.uwss.local.userDetailsLoader.resource' Environment property to a valid Spring Resource expression ('classpath:', 'file:', etc).

PviAttributeBindingFilter is a filter that binds the currently
authenticated user's PVI to the request as an attribute with the key
"wiscedupvi".

Switch to Map<String, String> for attributes

Using a Map allows for multiple attributes to be added to the request.

Change to AttributeBindingFilter for user specific attributes

Filter supports UWUserDetails style attributes (such as `wiscedupvi`) for
adding attributes specific to an authenticated user to a request.

Change to PviAttributeBindingFilter

The filter only needs to add a user's PVI as an attribute.

Add type check for principal

Principal is not always guaranteed to be a UWUserDetails instance at the
point it will hit this filter.
