Pull user's 'Full Name' attribute from OAuth source

[Mo0rBy]

Feature Description

I would like to be able to automatically add a user's Full Name attribute from the OAuth source they use to login.

The access token contains this information, but I don't see anywhere in the code that pulls this data and populates the user's Full Name attribute. It looks like it needs to be set manually.
I also checked the config cheatsheet to see if there were any settings that looked like they would do this, and I couldn't see anything.

Thinking about this, it might also be worth doing some value setting hierarchy, so the Full Name attribute is set by the OAuth2 authentication source's token, but if it is manually overwritten by the user, then this takes precedence.
