Fix linting errors in src/local/butler/scripts/setup.py

[jonathanmetzman]

They look like they are from the python upgrade:

src/local/butler/scripts/setup.py:372:17: E1101: Instance of 'MetricServiceClient' has no 'project_path' member (no-member)
src/local/butler/scripts/setup.py:385:8: E1121: Too many positional arguments for method call (too-many-function-args)
src/local/butler/scripts/setup.py:389:8: E1121: Too many positional arguments for method call (too-many-function-args)

There is a migration guide to monitoring >=2.0, from this stack overflow post. Gonna look into this

#4062

Verified the setup.py butler script works, this should do the trick

python butler.py run setup --config-dir ../clusterfuzz-config/configs/internal --non-dry-run
...

Done

Please remember to run the migration individually on all projects.
