Currently pegging.py is run indepdently instead of using rpc-tets.py like the rest. Currently: ``` python3 ./qa/rpc-tests/pegging.py /home/myhost/bitcoin-0.15.1/bin/ ``` We should move to something like: ``` python3 ./qa/pull-tester/rpc-tests.py feature_fedpeg --parent-binary=/home/myhost/bitcoin-0.15.1/bin/ ``` while still maintaining the existing test passing by using its same binary for the parent chain: ``` python3 ./qa/pull-tester/rpc-tests.py feature_fedpeg ```
