feat: new LocalUserDetailsLoader for populating local-users store

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).

Clean up stale javadocs.

The same ObjectMapper instance with a YAMLFactory can load both YAML and JSON.

Define userName variable distinct from eppn in federated mapper

This change is motivated by the need to set userName to a value other than default value of eppn for federated preauthenticated users.  The intended use case is UW Digital ID, where we plan to use SPVI as the username for the purposes of the RequestOnBehalfOfFilter.

fix: correct configuration to activate federation attributemapper

We can't just decorate the `FederatedPreauthenticatedUserDetailsAttributesMapper` with @Component, because the package edu.wisc.uwss.preauth isn't @ComponentScan'ned (edu.wisc.uwss.configuration.preauth is, by design).

Corrected the logger for the Federated attributesmapper, it was incorrectly using the Default implementation (so you couldn't tell which class was lgogging).

Added a Maven profile to help test: combined-simulate-federation.

Add preauth mapper for UW System authenticated user. Bump to version 1.3.0

Creates an alternative  to the default Preauth attributes mapper (which is UW-Madison focused) that is specific to the common attributes for an authenticated UW System user.  

Note that in the System context eppn replaces uid as the response for usernameHeader, because uid is no longer a meaningful identifier in a federated context where the bare uid might not be unique unless it's scoped to an individual campus. 

The more the merrier: @paul.erickson @ahoffmann

Add support for deprecated mapping

To add backwards compatibility, additional mappings were added in the Attribute mapping.  Unit tests confirmed successful mapping.

feat: Add optional REST Controller to simulate Shibboleth's session handler

This pull requests adds an optional REST Controller to simulate a response that matches the exact JSON format of Shibboleth's session handler.

Example: log in to https://test.my.wisc.edu. After completing login, visit https://test.my.wisc.edu/Shibboleth.sso/Session.json.

This controller is not active by default; in order to add it, activate the Spring Profile named `edu.wisc.uwss.simulated-shibboleth`.

Sample response for Amy Administrator:

```
{
  expiration: 480,
  client_address: "0:0:0:0:0:0:0:1",
  protocol: "urn:oasis:names:tc:SAML:2.0:protocol",
  identity_provider: "https://logintest.wisc.edu/idp/shibboleth",
  authn_instant: "2016-05-16T17:40:37.762",
  authncontext_class: "urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport",
  attributes: [
    {
      name: "persistent-id",
      values: [ "https://logintest.wisc.edu/idp/shibboleth!https://fake.wisc.edu/shibboleth!thisis/fake/PE="
]
    },
    {
      name: "uid",
      values: [ "admin" ]
    },
    {
      name: "pubcookie-user",
      values: [ "admin" ]
    },
    {
    name: "wiscEduPVI",
    values: [ "UW000A000" ]
    }
  ]
}
```

The idea for this came from a discussion with @levett.
