[Request] Added username and emailAddress to extensions

[kelvinspencer]

Description

• This PR is in reference to a few requests I noticed under issues that were closed, as well as a similar need for a project I am working on. The need is to be able to include an email address in addition to a username to the actor. Unfortunately since we cannot add to the actor schema, I noticed guidance in the comments that the requester should consider adding additional profile attributes to the extensions schema. Reference: Adding custom user profile fields #87 (comment).

• Please comment if there is an alternative option for including both username and email in the actor schema instead, without modifying the plugin to vastly.

Considerations

• Leverage Groups in the Actor Schema (Require larger modification of plugin to accomplish than enhancing extensions)
• Add to Extensions schema (Selected)
• Develop new schema (Large level of effort)
• Add to Actor schema (Can't due to restrictions)

Tests

• Not yet completed, waiting until confirmed solution is logical and sound by maintainers.
• Manually tested and confirmed working in the environment I'm actively supporting.
