[keycloak-dev] Importing json from 1.1.0 into 1.2.0

I came up with a simple solution to import json from 1.1.0 to 1.2.0. In RealmRepresentation and UserRepresentation the old social properties are re-added with a @Deprecated. In RepresentationToModel the first thing that's done is to convert these to the new identity brokering properties. For details see https://github.com/keycloak/keycloak/commit/8a38597b3acdb568d794d1d424961... If we do the same for claims to protocol-mappers we should be fine with importing json representations from 1.1.0.Final into 1.2.0.Beta1.
