Add SendGrid Categories

Add categories field to the Email Provider screen at a minimum, but preferably at the template level.

SendGrid has a categories field that allows users to add a string for tracking and/or email categorization.

When Auth0 sends an email via SendGrid and the user says they are not receiving it, I have to check our Auth0 logs to see when the email was sent and query my SendGrid logs for the particular user. I look around the time frame the email should be sent.
Having the ability to add categories would help me quickly identify Auth0’s email and tell me which emails were sent by Auth0 without having to guess based on a time frame.
