Bug 2005242 - Switch Default AI Tab Grouping Method to Logistic Regression. r=tarek

This patch updates the default tab suggest method to logistic regression.
This new approach adds domain handling and improves upon the existing nearest
neighbor approach by ~20% F1 on our evaluation data. We should see an increase
in suggestions and approval rate with this update (in theory).
