KEYCLOAK-1881 Include key ID for REDIRECT and use it for validation

Browse source 
Contrary to POST binding, signature of SAML protocol message sent using
REDIRECT binding is contained in query parameters and not in the
message. This renders <dsig:KeyName> key ID hint unusable. This commit
adds <Extensions> element in SAML protocol message containing key ID so
that key ID is present in the SAML protocol message.
