fedcode-next: Extract fix commits from the commit logs in search for CVE-related commit messages

[pombredanne]

We should create a pipeline that extract fix commits by parsing commit messages there is multiple way we for doing that

• Use a single simple regular expression. ex CVE-\d{4}-\d{4,7}
• Apply multiple regular expressions with a k-top ranking strategy.
• Develop a machine learning model to extract the most relevant fix commits.
