Allow returning auth info as part to the response type

[00dav00]

What is the problem the enhancement will solve?

Some gql clients expect the auth info (token, client id and expiration date) to be part of the return type instead of taking them from the response headers

Describe the solution you have in mind

Add a field to the login mutation that includes auth info, it can be something like:

field auth_info, Types::AuthInfo, null: true

And the auth info type can look like this:

class Types::AuthInfo < GraphQL::Schema::Object
      field :access_token, String, null: false
      field :token_type, String, null: false
      field :client, String, null: false
      field :expiry, Date, null: true
      field :uid, String, null: false
end
