[tor-commits] [metrics-lib/master] Add support for six new key-value pairs added by OnionPerf.



commit ee696b09f02ae59e7dccf8a5eb68ca484051040e
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date:   Mon May 1 20:38:55 2017 +0200

    Add support for six new key-value pairs added by OnionPerf.
    
    OnionPerf adds six new key-value pairs to the .tpf format that
    Torperf/CollecTor did not produce: ENDPOINTLOCAL, ENDPOINTPROXY,
    ENDPOINTREMOTE, HOSTNAMELOCAL, HOSTNAMEREMOTE, and SOURCEADDRESS.
    
    We should add support for these keys to metrics-lib, so that we can
    start using their values.
    
    Implements #22122.
