Automatic userID tracking and blocking

[simon-id]

What does this PR do?

Adds automatic User ID tracking when using passport.js

Changes:

• Add instrumentation for passport deserializeUser
• Add an IAST weak hash exclusion for express-session as it's using SHA1 for diff checking.
• Make the user tracking SDK call the WAF whenever an ID or login is passed.
• Make the user tracking SDK add the _dd.appsec.user.collection_mode: 'sdk' tag.
• Use res.constructor.prototype.end() instead of res.end() in blocking.js to bypass express-session monkeypatch of that method.
• Add automated user tracking and blocking for passport module.
• Add instrum.user_auth.missing_user_id telemetry metric.
• Remove rootSpan check from trackLogin() as it's already checked by the caller.
• Add trackUser() method, called right after deserializeUser() finishes.
• Update all relevant tests.
