Background
* This is part of the work to support
a credential management app on
unmanaged devices.
Changes
* Add a preference controller which will only
be enabled if there is a credential management app.
* Add a fragment to display details on the credential
management app and its policy. Add a remove button
to remove the credential management app.
* Link CredentialManagementAppAdapter to new fragment
and add expander.
Manual Testing
* Verify preference is disabled if there is no credential
management app.
* Verify preference summary shows credential mangement
app name if a credential management app exists.
* Verify fragment details page displays the
authentication policy correctly.
