Add RFC for Notification Categories

Provide a useful mechanism for assigning notifications to taxonomies so they may be actioned upon differently under varying operating contexts.

Turning something like:

warning eslint > jshint > minimatch@0.4.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

Into something like:

warn [infosec] vulnerability detected in minimatch ...

We all yearn to reduce cognitive overhead during development. One such way of helping achieve that is to open a method by which packages may group like notifications into categories which may then be actioned upon in some way by the end-user via an API, be it CLI or configuration-based.

In turn taxonomies like [infosec] or [optim] enable parsable messages in buffered output for enhanced logging while adding value to end-users, if displayed.

Following a push notification model openens the ability to use OS-integrated notifiers to send important notifications to users via in-built tooling instead of only messaging on the CLI.
