Feature: Notification categories/severity/labels

[iampearceman]

🔖 Feature description

You should add more metadata options to make notification templates more configurable. Stuff like categories, labels or severity would make templates and notifications hold more information and it could extend Novu functionality. Users could choose their preferences based on these labels (e.g. send WARNING notifications by email and INFO in-app).

🎤 Why is this feature needed ?

We wanted to use Novu as our notification backend while wrapping the API to serve our own component, we found the notification/workflow/template model lacking, especially when we needed to categorize the notifications into specific categories and label them accordingly. More metadata options or extended template model would help.

✌️ How do you aim to achieve this?

• extend notification model with more metadata
• make this feature API-first friendly
