Include some sort of auth0 string in Custom Log Streams

Feature: Include some sort of auth0 string in Custom Log Streams

Description: We are streaming auth0 logs to new relic via a custom log stream. In NR we also have other logs not related to auth0 and there is no way of filtering which logs come from auth0 and which don’t. There isn’t a specific field that we can filter by eg: source: auth0

Use-case: We want to have all our app logs in NR, so we built a custom log stream to add Auth0 logs to NR and have all logs in one place.
