B503: Test for SSL use with bad defaults specified

This plugin is part of a family of tests that detect the use of known bad versions of SSL/TLS, please see B503: ssl_with_bad_version for a complete discussion. Specifically, this plugin test scans for Python methods with default parameter values that specify the use of broken SSL/TLS protocol versions. Currently, detection supports methods using Python’s native SSL/TLS support and the pyOpenSSL module. A MEDIUM severity warning will be reported whenever known broken protocol versions are detected.
