mod_http_oauth2: Record OAuth software id and version attached to tokens Unsure if these are used anywhere, but `software_id` is supposedly more unique than `client_uri` which can vary by registration or something? Software versions can also be good to know e.g. in case there is a security issue affecting certain versions that could warrant revocation of tokens issued to it.
