KEYCLOAK-1881 Include key ID in <ds:KeyInfo> in SAML assertions and protocol message

Browse source 
Changes of SAML assertion creation/parsing that are required to allow
for validation of rotating realm key: signed SAML assertions and signed
SAML protocol message now contain signing key ID in XML <dsig:KeyName>
element.
