Closes #12226: Add Profile Data Headers to Remote Authentication Middleware

[stuntguy3000]

Fixes: #12226

This change introduces a new set of optional headers which update the user's profile when using Remote Authentication.

The original issue references specifically first names, however this change looks at the whole user's profile.

Quick note from the original request, it was Full Name rather than First Name - are they separate fields in the db? Most auth providers send the full name as one field.

[stuntguy3000]

That's my understanding of the data structure. Perhaps we could add a full name field and transpose it? But that the leaves it up to interpretation of how to split a name.

They are separate fields.

Ah yeah that looks to be the case. That's a tough one isn't it - so many different formats of name!

[heapdavid]

Apologies, it looks like we can get first and last name fields from our auth providers separately, so should be fine to proceed as is.
