[tor-commits] [metrics-lib/master] Ignore unknown fields in index.json.

commit fba9137499ef6255f040d134f488403cae214793
Author: Karsten Loesing <karsten.loesing@xxxxxxx>

    Ignore unknown fields in index.json.
    
    This is required for processing index.json files produced by CollecTor
    1.13.0 or higher. We don't need those newly added fields or any other
    fields added in the future. But we must not fail when fields are
    added.
