api: access: domains: add ExtraRealmInfo and RealmInfo structs

these will be used as parameters/return types for the read/create/etc.
calls for realms

for now we copy the necessary attributes (only from openid) since
our api macros/tools are not good enought to generate the necessary
api definitions for section configs
