Salt's pluggable authentication system
This system allows for authentication to be managed in a module pluggable way
so that any external authentication system can be used inside of Salt

Go through various checks to see if the token/eauth/user can be authenticated.
Returns a dictionary containing the following keys:
- auth_list
- username
- error
If an error is encountered, return immediately with the relevant error dictionary
as authentication has failed. Otherwise, return the username and valid auth_list.
