Configuring additional signing/encryption certificate/key pairs for IDP 3.4.6

[Cantor, Scott]

The wiring example for this is under Per-Profile Credential in the SecurityConfiguration page. The wiring is ugly.

The general hierarchy of objects is:

SecurityConfiguration
	SignatureSigningConfiguration
		List<Credential> (signingCredentials property).

You're attempting to skip the middle one. You can't inject the Credential (implicitly, a List of them) into a SecurityConfiguration bean, you need another object of type SignatureSigningConfiguration in between.
