trace: `verify` flag is not wired up to turn off cert validation for capturing traces

This is important to capture traces through proxy tools like fiddler which uses self-signed certificate.
The verify appears designed for such purpose, but it is not wired up in oauth2.py, nor is wired up in other places like authority.py

OK I'll take a look. By the way, you are using similar steps like this to generate your self-signed cert, aren't you?

No, but that link also works.

Or you can do this, which might be simpler

install azure-cli
run az ad sp create-for-rbac -n http://you-great-sp --create-cert --skip-assignment
